000 WTNT45 KNHC 190843 TCDAT5 Tropical Storm Nadine Discussion Number 3 NWS National Hurricane Center Miami FL AL152024 400 AM CDT Sat Oct 19 2024 ASCAT data from 0309 UTC showed that the disturbance over the northwestern Caribbean Sea had developed a closed circulation and well-defined center, with a swath of 30-35 kt winds extending north off the coast of the Yucatan Peninsula. Based on that information, the system was designated as Tropical Storm Nadine in the 1 AM CDT (0600 UTC) intermediate advisory. Satellite data and radar images from Belize indicate that Nadine's structure is broad but is gradually becoming better organized, and the latest Dvorak estimates from TAFB and SAB are T2.5/35 kt. Winds to tropical storm force have been measured along the coast as far north as Cancun. The scatterometer data showed that Nadine formed a little farther south than where the disturbance was previously estimated, but the initial motion is still westward (270 degrees) at 8 kt. Nadine should begin moving faster toward the west through the day while being steered by a mid-level ridge over the Gulf of Mexico. There is good agreement among the track models, and the NHC track forecast lies between the TVCA and HCCA consensus aids. On this track, Nadine's center should make landfall along the Belize coast sometime late morning or midday and then continue westward across northern Guatemala and southeastern Mexico late this afternoon into tonight. Some slight strengthening is possible this morning before Nadine reaches the coast due to low atmospheric wind shear and ocean temperatures around 29 degrees Celsius. Weakening is forecast after Nadine moves inland, and the storm should fall below tropical storm strength later this afternoon. Nadine is likely to dissipate over southeastern Mexico by early Sunday. Key Messages: 1. Localized areas of flash flooding are possible along the track of Nadine across southern Mexico, northern Guatemala, and northern Belize. 2. Tropical storm conditions are expected along portions of the coasts of Belize and the Yucatan Peninsula of Mexico within the warning area through this afternoon.

SUMMARY OF 1000 PM CDT...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...17.6N 86.1W ABOUT 140 MI...225 KM E OF BELIZE CITY MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...W OR 275 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...1005 MB...29.68 INCHES WATCHES AND WARNINGS -------------------- CHANGES WITH THIS ADVISORY: None. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Watch is in effect for... * Belize City, Belize to Tulum, Mexico A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 12-24 hours. Interests elsewhere in Belize and the Yucatan Peninsula of Mexico 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 1000 PM CDT (0300 UTC), the disturbance was centered near latitude 17.6 North, longitude 86.1 West. The system is moving toward the west near 8 mph (13 km/h), and this general motion should continue through Saturday night. On the forecast track, the system is expected to move inland along the coast of Belize on Saturday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some gradual strengthening is anticipated, and the disturbance is forecast to become a tropical storm before making landfall tomorrow. * Formation chance through 48 hours...high...80 percent. * Formation chance through 7 days...high...80 percent. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Potential Tropical Cyclone Fifteen can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC and on the web at hurricanes.gov/text/MIATCDAT5.shtml RAINFALL: Widespread 4-8 inch rainfall amounts are expected across northern Belize, northern Guatemala, and the southern states of Mexico from Quintana Roo westward to Veracruz. Isolated areas of amounts exceeding 12 inches are also possible through late Tuesday. For a complete depiction of forecast rainfall associated with Potential Tropical Cyclone Fifteen, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at5.shtml?rainqpf WIND: Tropical storm conditions are possible within the watch area on Saturday. STORM SURGE: Minor coastal flooding is possible in areas of onshore flow near and to the north of where the center moves inland. NEXT ADVISORY ------------- Next intermediate advisory at 100 AM CDT. Next complete advisory at 400 AM CDT. $$ Forecaster Reinhart

000 WTNT45 KNHC 190239 TCDAT5 Potential Tropical Cyclone Fifteen Discussion Number 2 NWS National Hurricane Center Miami FL AL152024 1000 PM CDT Fri Oct 18 2024 The satellite presentation of the disturbance has improved this evening. Curved bands of deep convection have developed closer to the estimated center position, although it is unclear from recent passive microwave imagery whether a well-defined surface center exists yet. The strongest winds are occurring within the convective bands to the north of the center, where NOAA buoy 42056 has reported sustained winds of 25-30 kt and gusts to tropical storm force. Based on these observations and available satellite data, the system will remain a 30-kt potential tropical cyclone for this advisory. Data from an ASCAT-C overpass will arrive within the next couple of hours, which should provide some clarity about the current intensity of the system and whether it has a well-defined center. The disturbance appears to be moving westward at about 7 kt to the south of a high pressure ridge over the eastern United States. The latest track guidance agrees that the system should continue on a westward heading through Saturday night and cross the coast of Belize between 12-24 h from now. The latest NHC track forecast is very similar to the previous prediction and remains close to the multi-model consensus aids. Despite limited time remaining over water, warm SSTs and relatively low shear in a moist environment should allow the system to consolidate and strengthen into a tropical storm before it moves ashore. The strongest winds are forecast to occur within the northern semicircle, and a Tropical Storm Watch remains in effect from Belize City northward to Tulum, Mexico. Weakening is expected once the system moves inland, and it is forecast to dissipate over southern Mexico by early Sunday. Key Messages: 1. Potential Tropical Cyclone Fifteen is expected to bring impacts from heavy rain, coastal flooding, and high surf to portions of Belize and the Yucatan Peninsula of Mexico this weekend. Localized areas of flash flooding are possible as the system moves westward through southern Mexico, northern Guatemala, and northern Belize. 2. Tropical storm conditions are possible along portions of the coasts of Belize and the Yucatan Peninsula of Mexico within the Tropical Storm Watch area by early Saturday.
