Interests elsewhere in the Yucatan Peninsula should monitor the progress of this system. 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 Sara was located near latitude 16.6 North, longitude 87.6 West. Sara is moving toward the west-northwest near 5 mph (7 km/h), and this general motion with some increase in forward speed is expected until landfall. On the forecast track, the center of Sara will move over Belize later today. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is anticipated until landfall later today, with dissipation expected over the southern portion of the Yucatan Peninsula by early Monday. Tropical-storm-force winds extend outward up to 105 miles (165 km), primarily north of the center. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key Messages for Tropical Storm Sara can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC and on the web at hurricanes.gov/text/MIATCDAT4.shtml RAINFALL: Through early next week, rainfall amounts of 15 to 25 inches with isolated storm totals around 40 inches are expected over northern Honduras. This rainfall will lead to widespread areas of life-threatening and potentially catastrophic flash flooding and mudslides, especially along and near the Sierra La Esperanza. Elsewhere across the rest of Honduras, Belize, El Salvador, eastern Guatemala, western Nicaragua, and the Mexican State of Quintana Roo, Tropical Storm Sara is expected to produce 5 to 10 inches of rain with localized totals around 15 inches through early next week. This will result in areas of flash flooding, perhaps significant, along with the potential of mudslides. For a complete depiction of forecast rainfall associated with Tropical Storm Sara, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/refresh/graphics_at4+shtml/205755.shtml? rainqpf#contents WIND: Tropical storm conditions, especially in gusts, are expected in the warning area in portions of Honduras, Guatemala, Belize, and portions of Mexico today. STORM SURGE: Storm surge could raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast in areas of onshore winds along the northern coast of Honduras. Near the coast, the surge will be accompanied by large and destructive waves. A storm surge could raise water levels by as much as 1 to 3 feet above ground level near and to the north of where the center of Sara crosses the coast of Belize.

000 WTNT44 KNHC 170233 TCDAT4 Tropical Storm Sara Discussion Number 14 NWS National Hurricane Center Miami FL AL192024 900 PM CST Sat Nov 16 2024 Sara remains a poorly organized tropical storm, with the most significant banding features in the northern semicircle well away from the low-level center. Air Force Reserve Hurricane Hunter flight-level and dropsonde data indicate that the central pressure has risen to 1001 mb and the winds have decreased. The initial wind speed is set to 35 kt, which are mostly occurring in the rain bands well away from the center. Aircraft fixes indicate the storm is moving slowly to the west-northwest. Sara should slightly accelerate in that direction as mid-level ridging strengthens over the Gulf of Mexico through tomorrow. The storm is expected to make landfall on Sunday on the coast of Belize, and very little change was made to the NHC forecast with guidance consistent from the last cycle. Little change in intensity is expected before landfall due to the disorganized nature of Sara, and the new intensity forecast is slightly lower than the last one. The weakened cyclone should dissipate over the southern portion of the Yucatan peninsula by early Monday. The primary hazard associated with Sara continues to be potentially catastrophic flash flooding, with substantial rainfall continuing to occur near the north coast and in upslope regions of higher terrain in Honduras. KEY MESSAGES: 1. Through early next week, heavy rainfall from Tropical Storm Sara will cause potentially catastrophic flash flooding and mudslides over northern portions of Honduras. 2. Elsewhere across Belize, El Salvador, eastern Guatemala, western Nicaragua, and the Mexican State of Quintana Roo, heavy rainfall will cause significant and life-threatening flash flooding and mudslides. 3. Tropical storm conditions are expected along portions of the northern coast of Honduras, the Bay Islands, the Caribbean coast of Guatemala, the coast of Belize, and portions of the coast of Mexico where tropical storm warnings are in effect.

000 WTNT44 KNHC 162042 TCDAT4 Tropical Storm Sara Discussion Number 13 NWS National Hurricane Center Miami FL AL192024 300 PM CST Sat Nov 16 2024 Sara's center has been pretty easy to find this afternoon, with 1-minute visible satellite imagery showing the low level center beginning to move westward away from the Bay Islands of Honduras and more into the Gulf of Honduras. An Air Force Reserve reconnaissance mission flew through the center this afternoon, indicating little change in Sara's intensity with a 1000 mb pressure, peak 850 mb flight-level winds of 44 kt, and a dropsonde launched in the southwestern side of the circulation also indicating a surface wind gust of 37 kt. The initial intensity is held at 40 kt for this advisory, though this could be a little generous based on the aircraft observations. The tropical storm now appears to be moving a bit faster to the west, with the motion estimated at 280/4 kt. Mid-level ridging is beginning to develop to the northeast of Sara and should help continue to move the system westward to west-northwestward until the tropical storm makes landfall in Belize at some point tomorrow morning. The NHC track forecast this cycle has been shifted a bit southward early on, partially related to initial position updates, but still lies near the center of the track guidance envelope. Intensity-wise, Sara's circulation has been significantly disrupted despite remaining just offshore. The broader circulation of the tropical storm has been interacting with the mountainous terrain of northern Honduras, and I suspect that some of the drying downslope flow off this higher terrain is playing some role in why Sara is struggling to produce much deep convection near its center currently. In fact most of the remaining convection is organized in fragmented bands well to the north of the center. Despite the relatively favorable environmental conditions, the current structure of Sara argues against much intensification before it moves inland over Belize in about 18 h, and the latest forecast shows little change in strength before landfall. After moving inland, weakening should commence and the global and hurricane-regional model guidance continue to indicate Sara will open up into a trough as it emerges into the Gulf of Mexico. However its remnant moisture will continue to propagate northward and likely act as a focal point for enhanced precipitation ahead of the next frontal boundary along the northern Gulf coast by the middle of this week. As stressed over the past couple of days, the primary hazard associated with Sara remains catastrophic flash flooding, with substantial rainfall continuing to occur near the north coast and in upslope regions of higher terrain in Honduras. KEY MESSAGES: 1. Through early next week, heavy rainfall from Tropical Storm Sara will cause potentially catastrophic flash flooding and mudslides over northern portions of Honduras. 2.

000 WTNT44 KNHC 161442 TCDAT4 Tropical Storm Sara Discussion Number 12 NWS National Hurricane Center Miami FL AL192024 900 AM CST Sat Nov 16 2024 Satellite imagery depicts that the center of Sara is located near the Bay Islands of Honduras. The overall convective structure is fairly disorganized, with a broken curved band on the northwest side, and less convection near the center of circulation. Satellite intensity estimates have decreased this advisory, although the initial intensity is held steady at 40 kt, based on earlier scatterometer data showing 35-40 knots over the western semicircle. An Air Force Reserve Hurricane Hunter aircraft is en route to investigate the system, which should help better determine the structure and intensity. The storm appears to have started to drift west-northwestward with an estimated motion of 290/02 kt. A mid-level ridge should strengthen to the northeast of Sara later today, which is forecast to cause the tropical cyclone to move toward the west-northwest through Sunday, with a slight increase in forward speed. On the forecast track, the system should make landfall in Belize just beyond the 24 h forecast point. After landfall, Sara or its remnants should turn northwestward as it moves across the southern portion of the Yucatan Peninsula. The latest NHC forecast track is similar to the previous and lies near the middle of the guidance envelope. The current intensity forecast is for the system to hold steady through landfall which is in good agreement with the intensity guidance. Although, some intensity fluctuations are possible as Sara moves over the Gulf of Honduras and approaches Belize during the next 24 h. After landfall, the storm will weaken and models are in good agreement that it should dissipate and open into a trough over the Yucatan Peninsula before reaching the Bay of Campeche or the Gulf of Mexico. Based on this model guidance, the intensity forecast shows dissipation at 60 h, although that could occur sooner. The remnants of Sara could interact with a frontal system to enhance convection near the northern Gulf coast in the early or middle part of next week. The primary hazard associated with Sara will continue to be catastrophic flash flooding, with preliminary reports already suggesting substantial rainfall has occurred near the north coast and in upslope regions of higher terrain in Honduras. KEY MESSAGES: 1. Through early next week, heavy rainfall from Tropical Storm Sara will cause potentially catastrophic flash flooding and mudslides over northern portions of Honduras. 2. Elsewhere across Belize, El Salvador, eastern Guatemala, western Nicaragua, and the Mexican State of Quintana Roo heavy rainfall will cause significant and life-threatening flash flooding and mudslides. 3. Tropical storm conditions are expected along portions of the northern coast of Honduras, the Bay Islands, the Caribbean coast of Guatemala, the coast of Belize, and portions of the coast of Mexico where tropical storm warnings are in effect.

000 WTNT44 KNHC 160839 TCDAT4 Tropical Storm Sara Discussion Number 11 NWS National Hurricane Center Miami FL AL192024 300 AM CST Sat Nov 16 2024 Satellite imagery and recent scatterometer data indicate that the center of Sara is located between the coast of mainland Honduras and the Bay Islands. Compared to 24 h ago, the storm has become less organized with a decrease in the convection near the center. The ASCAT data showed maximum winds of 35-40 kt in an area of convection to the west and northwest of the center, and based on this the initial intensity is lowered to 40 kt. The cyclone remains stationary. A mid-level ridge should strengthen to the north of Sara later today or tonight, which is forecast to cause the tropical cyclone to move slowly toward the west-northwest through Sunday. This motion should bring the center over Belize between the 24-36 h points. After landfall, Sara or its remnants should turn northwestward as it moves across the southern portion of the Yucatan Peninsula. The intensity guidance is in good agreement that not much change in strength should occur before Sara makes landfall in Belize. The intensity forecast will show a little strengthening at 24 h when the system has the most room over water. The cyclone should weaken after landfall, and the dynamical models are in good agreement that it should decay to a open trough before reaching the Bay of Campeche or the Gulf of Mexico. Based on this guidance, the intensity forecast now shows dissipation by 60 h. The global models suggest the possibility that the remnants of Sara could interact with a frontal system to form a non-tropical low near the northern Gulf coast in the early or middle part of next week. The primary hazard associated with Sara will continue to be catastrophic flash flooding, with preliminary reports already suggesting substantial rainfall has occurred near the north coast and in upslope regions of higher terrain in Honduras. KEY MESSAGES: 1. Through early next week, heavy rainfall from Tropical Storm Sara will cause potentially catastrophic flash flooding and mudslides over northern portions of Honduras. 2.
