as Tropical Storm watches may be required later today or tonight
for portions of these areas.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 900 AM CST (1500 UTC), the center of Tropical Depression Eta was
located near latitude 15.1 North, longitude 87.8 West. The
depression is moving toward the northwest near 9 mph (15 km/h), and 
this general motion is expected to continue today.  A turn toward 
the north, and then the northeast is forecast to occur tonight and 
Friday.  On the forecast track, the center of Eta is expected to 
move across northwestern Honduras through this afternoon, and 
emerge over the Gulf of Honduras by tonight.  Eta is forecast to 
approach the Cayman Islands and western or central Cuba this 
weekend.
 
Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. 
Little change in strength is likely through tonight.  After that, 
Eta is forecast to intensify over the northwestern Caribbean Sea.
 
The estimated minimum central pressure is 1005 mb (29.68 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Eta can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT4, WMO header WTNT44 KNHC, and on the
web at www.hurricanes.gov/text/MIATCDAT4.shtml.
 
RAINFALL: Eta is expected to produce the following rainfall amounts
through Tuesday morning:
 
Portions of Central America: An additional 10 to 15 inches (255 to
380 mm), isolated maximum storm totals of 40 inches (1000 mm) in
eastern Honduras and eastern Nicaragua.
 
Southeastern Mexico: 5 to 10 inches (125 to 255 mm), isolated
maximum totals of 20 inches (510 mm).
 
Jamaica: An additional 3 to 5 inches (75 to 125 mm), isolated
maximum storm totals of 15 inches (380 mm).
 
The Cayman Islands into portions of Cuba: 10 to 20 inches (255 to
510 mm), isolated maximum totals of 30 inches (760 mm).
 
This rainfall will lead to catastrophic, life-threatening flash
flooding and river flooding, along with landslides in areas of
higher terrain of Central America.  Significant, life-threatening
flash flooding and river flooding is possible in the Cayman Islands
and Cuba.  Flash flooding and river flooding is expected for Jamaica
and southeast Mexico.
 
SURF:  Swells generated by Eta are expected to affect portions of
the coast of Central America and the Yucatan Peninsula of Mexico
during the next couple of days.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
products from your local weather office.

Tropical Depression Eta Discussion Number  20
NWS National Hurricane Center Miami FL       AL292020
900 AM CST Thu Nov 05 2020

Eta remains disorganized this morning, as visible imagery suggests 
that the circulation has become elongated and that multiple 
vorticity centers may be present inside the larger cyclonic 
envelope.  The center position for this advisory, which is over 
northwestern Honduras, is closer to convection in the northwestern 
semicircle than was the case 6 h ago, so the cyclone is being 
maintained as a tropical depression at this time.
 
The initial motion is a somewhat uncertain 305/8 kt.  Eta or its 
remnants should move generally northwestward today, then turn 
northward tonight. From 24-72 h, the system should move 
northeastward in response to a developing mid- to upper-level 
trough over the central and eastern Gulf of Mexico.  From 72-120 h, 
the trough is forecast to become a closed mid- to upper-level low 
in the vicinity of western Cuba, with the center of Eta likely to 
turn west-northwestward on the north side of the low.  While the 
global models are in good agreement with this synoptic evolution, 
there is a significant spread in the forecast tracks between the 
fastest and farthest east GFS and the slowest and farthest west 
UKMET.  The new forecast track lies between these extremes in best 
overall agreement with the ECMWF and Canadian models, and it calls 
for the system to be near western Cuba and the Cayman Islands in 
60-72 h, and then be over the southeastern Gulf of Mexico by the 
end of the forecast period.

Little change in strength is expected before the center moves back 
over the Caribbean, but there is still a chance that Eta could 
degenerate to a remnant low pressure area later today if the 
convection does not persist.  Intensification is expected over the 
warm waters of the Caribbean Sea from 24-72 h, although this may be 
slowed by southwesterly shear caused by the aforementioned trough.  
As the trough cuts off near or over Eta between 72-120 h, the 
global models suggest that the system could strengthen while 
acquiring at least some subtropical or hybrid characteristics due 
to upper-level cold air entrainment.  The new intensity forecast is 
little changed from the previous forecast, and in the latter part of 
the forecast period it lies near the intensity consensus.  It should 
be noted that while Eta regaining hurricane strength cannot be ruled 
out, there is little support for that in the current guidance.
 
Key Messages:
 
1. Through Monday morning, heavy rainfall from Eta will lead to
catastrophic, life-threatening flash flooding and river flooding
across portions of Central America, along with landslides in areas
of higher terrain.  Flash and river flooding is also possible across
Jamaica, southeast Mexico, the Cayman Islands and western Cuba.
 
2. Eta is forecast to regain tropical storm strength over the
northwestern Caribbean Sea late this week. Although the details of
the future track and intensity of Eta are uncertain, there is an
increasing risk of impacts from wind and rainfall in portions of 
the Cayman Islands, Cuba, southern Florida and the Florida Keys 
this weekend and early next week.

Remnants Of Iota Discussion Number  21
NWS National Hurricane Center Miami FL       AL312020
900 AM CST Wed Nov 18 2020

Although the system still has broad mid-level rotation, synoptic 
observations from Central America show that the surface circulation 
of Iota has dissipated.  Its remnants are located somewhere near El 
Salvador.

Although the remnants of Iota are likely to move into the eastern 
North Pacific during the next day or so, the global models do not 
show regeneration of the system over that basin.

Iota is still expected to produce very serious flash flooding and
mudslides, with potentially catastrophic effects, over 
portions of Central America.

This is the last advisory issued by the National Hurricane Center 
on Iota.

 
Key Messages:
 
1.  Life-threatening flash flooding and river flooding is expected
through Thursday across portions of Central America due to heavy
rainfall from the remnants of Iota.  Flooding and mudslides across 
portions of Honduras, Nicaragua and Guatemala could be exacerbated 
by saturated soils in place, resulting in significant to 
potentially catastrophic impacts.

Tropical Depression Iota Discussion Number  20
NWS National Hurricane Center Miami FL       AL312020
300 AM CST Wed Nov 18 2020
 
Deep convection is no longer occurring near Iota's center, but 
curved broken bands of convection still exist within 100 n mi in 
the northern semicircle. For that reason, Iota is being maintained 
as a tropical cyclone. Earlier ASCAT and ScatSat scatterometer data 
between 0200-0300 UTC indicated surface winds of 30-32 kt offshore 
the north-central coast of Honduras, while tropical-storm-force wind 
gusts were noted in surface observations along the north coast of 
Honduras. As a result, the intensity was maintained at 35 kt at the 
0600 UTC synoptic time. Since then, however, winds have decreased 
along the coast and offshore, which justify making Iota a 30-kt 
tropical depression at the 0900 UTC advisory time. Therefore, the 
Tropical Storm Warning for the northern coast of Honduras has been 
discontinued.

The initial motion estimate is now 255/11 kt. Iota or its remnants 
should continue moving west-southwestward across El Salvador, 
possibly emerging over the eastern North Pacific Ocean as a 
post-tropical cyclone before dissipation occurs by late today. At 
this time, most of the available NHC model guidance does not show 
regeneration over the eastern Pacific, with only the HWRF and HMON 
regional models showing brief redevelopment to tropical depression 
status on Thursday after Iota degenerates to a remnant low later 
today. However, this is considered a low probability alternate 
scenario due to unfavorable upper-level winds expected across the 
eastern North Pacific.
 
Iota is still expected to produce very serious flash flooding and 
mud slides. These hazards could result in potentially catastrophic 
effects, especially when compounded upon Hurricane Eta's destruction 
from a couple of weeks ago.
 
Key Messages:
 
1.  Life-threatening flash flooding and river flooding is expected 
through Thursday across portions of Central America due to heavy 
rainfall from Iota. Flooding and mudslides across portions of 
Honduras, Nicaragua and Guatemala could be exacerbated by saturated 
soils in place, resulting in significant to potentially catastrophic 
impacts.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
 
A Tropical Storm Warning is in effect for...
* The coast of Honduras west of Punta Castilla to the
Honduras/Guatemala border
* Bay Islands
 
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.
 
For storm information specific to your area, please monitor
products issued by your national meteorological service.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 1200 AM CST (0600 UTC), the center of Tropical Storm Iota was
located near latitude 13.7 North, longitude 87.8 West. Iota is
moving toward the west near 12 mph (19 km/h), and a westward to
west-southwestward motion is expected through today.  On the
forecast track, the center of Iota will move across portions of
southern Honduras and El Salvador before the system dissipates later
today.
 
Maximum sustained winds are near 40 mph (65 km/h) with higher
gusts. Rapid weakening is forecast, and Iota should weaken to a
tropical depression later this morning and degenerate into a remnant
low pressure area by this afternoon.
 
Tropical-storm-force winds extend outward up to 185 miles (295 km)
from the center, mainly along the coast in the Tropical Storm
Warning area.  Recent satellite-derived wind data indicate that
tropical-storm-force wind gusts are still occurring along the
northwestern coast of Honduras.
 
The estimated minimum central pressure based on nearby surface
observations is 1005 mb (29.68 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
Key messages for Iota can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT1, WMO header WTNT41 KNHC
and on the web at www.hurricanes.gov/text/MIATCDAT1.shtml.
 
WIND:  Tropical-storm conditions will continue for a couple of more
hours well to the north of the center along the Caribbean coast of
northwestern Honduras.
 
RAINFALL:  Iota is expected to produce the following additional
rainfall accumulations through Thursday:
 
El Salvador, Panama, western Honduras, northern Nicaragua, southern
Belize  : 4 to 8 inches (100 to 200 mm), with isolated maximum
totals of 12 inches (300 mm).
 
This rainfall will lead to significant, life-threatening flash
flooding and river flooding, along with mudslides in areas of higher
terrain.
 
Southern Nicaragua and Costa Rica: 3 to 5 inches (75 to 125 mm),
with isolated maximum totals of 10 inches (250 mm).
 
SURF:  Swells generated by Iota will affect much of the coast of
Central America and the Yucatan Peninsula during the next day or so.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.

Hurricane Iota Discussion Number  17
NWS National Hurricane Center Miami FL       AL312020
900 AM CST Tue Nov 17 2020
 
Satellite images indicate that Iota continues to weaken over land 
with warming cloud tops near the center. It still has a small core, 
however, so the initial wind speed will be lowered to 65 kt on this 
advisory, in line with the Decay-SHIPS model.  Further weakening is 
expected today as Iota moves westward at about 10 kt, with Iota 
becoming a tropical storm this afternoon, and a tropical depression 
tonight.  Iota should degenerate into a remnant low near El Salvador 
by tomorrow due to the rugged terrain of central America.
 
While the winds of Iota are weakening, there are still life-
threatening hazards ongoing for central America, including flash
flooding and mud slides, which could result in potentially
catastrophic effects, especially when compounded upon Hurricane
Eta's destruction from a couple of weeks ago.
 
Key Messages:
 
1.  Life-threatening flash flooding and river flooding is expected
through Thursday across portions of Central America due to heavy
rainfall from Iota. Flooding and mudslides across portions of
Honduras, Nicaragua and Guatemala could be exacerbated by Hurricane
Etas recent effects there, resulting in significant to potentially
catastrophic impacts.
 
2.  Strong winds, primarily close to the center of Iota and along
the coasts of Nicaragua and Honduras, are still expected for the
next several hours.

DISCUSSION AND OUTLOOK
----------------------
At 900 AM CST (1500 UTC), the center of Hurricane Iota was located
near latitude 13.7 North, longitude 85.2 West. Iota is moving toward
the west near 12 mph (19 km/h).  The hurricane will move farther 
inland across northern Nicaragua today, and move across southern 
Honduras tonight before dissipating near El Salvador early 
Wednesday.
 
Maximum sustained winds have decreased to near 75 mph (120 km/h) 
with higher gusts.  Iota should weaken to a tropical storm this 
afternoon, a tropical depression this evening, and degenerate into 
a remnant low pressure area on Wednesday.
 
Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 175 miles
(280 km).
 
The estimated minimum central pressure is 980 mb (28.94 inches).

Hurricane Iota Discussion Number  16
NWS National Hurricane Center Miami FL       AL312020
400 AM EST Tue Nov 17 2020
 
Iota made landfall as a Category 4 hurricane along the northeastern 
coast of Nicaragua around 0340 UTC, near the town of Haulover. 
Iota's landfall location was about 12 nmi south of where Category 4 
Hurricane Eta made landfall earlier this month on November 3rd. Due 
to the previous damage caused by Eta, wind reports have been 
extremely limited. There was an amateur radio report from Club de 
Radio-Experimentadores de Nicaragua of 124 mph (200 Km/h) winds and 
roofs damaged in the town of Wilbi, Nicaragua. However, it is 
uncertain if these were sustained winds or wind gusts. At the Puerto 
Cabezas, Nicaragua, airport at 0253 UTC, a sustained wind of 72 kt 
(134 km/h) and a gust to 98 kt (182 km/h) were measured. The initial 
intensity of 90 kt is based on the Decay-SHIPS model's weakening 
rate for inland tropical cyclones, and the remnant eye feature 
still noted in infrared satellite imagery.
 
Iota is moving westward, or 270/08 kt. Iota is expected to continue 
moving generally westward today into early Wednesday, as the cyclone 
moves along he southern periphery of a deep-layer subtropical ridge 
located over the northern Caribbean Sea, the Gulf of Mexico, and 
southeastern Mexico. The lower levels of the ridge are forecast to 
push southward behind a cold front, which will force Iota and its 
remnants west-southwestward across southern Honduras and El Salvador 
in the 24-36 hour period. Iota is expected to dissipate by 48 hours, 
with the remnant mid-level circulation possibly drifting westward 
into the eastern North Pacific basin. The new NHC track forecast is 
essentially just an extension of the previous advisory track, and 
closely follows a blend of the consensus models TVCN, NOAA-HCCA, and 
FSSE.

Additional rapid weakening is forecast for the next 36 hours as Iota 
moves farther inland over the rugged terrain of Nicaragua and 
Honduras. The new NHC intensity forecast is similar to the previous 
advisory and closely follows the Decay-SHIPS intensity guidance.
 
Although Hurricane Iota has moved inland, damaging winds are  
occurring inland, and also along the northeastern coast of 
Nicaragua, where a significant storm surge of 5-10 ft is still 
likely occurring. In addition to the destructive winds and storm 
surge, there will be the potential for up to 30 inches of rainfall. 
The situation is exacerbated by the fact that Iota is moving across 
the same general location that Category 4 Hurricane Eta did a 
little less than two weeks ago.
 
Key Messages:
 
1.  Iota is still a significant hurricane. Damaging winds and a
life-threatening storm surge are expected along portions of the
coast of northeastern Nicaragua during the next several hours, where
a hurricane warning is in effect.
 
2.  Life-threatening flash flooding and river flooding is expected 
through Thursday across portions of Central America due to heavy 
rainfall from Iota. Flooding and mudslides across portions of 
Honduras, Nicaragua and Guatemala could be exacerbated by Hurricane 
Etas recent effects there, resulting in significant to potentially 
catastrophic impacts.
