Tropical Storm Sara Forecast Discussion Number 5
2024-11-14 21:44:41| National Hurricane Center (Atlantic)
Issued at 400 PM EST Thu Nov 14 2024 000 WTNT44 KNHC 142044 TCDAT4 Tropical Storm Sara Discussion Number 5 NWS National Hurricane Center Miami FL AL192024 400 PM EST Thu Nov 14 2024 Convective banding associated with the cyclone continued to improve especially over the western semicircle of the system after the release of the 1500 UTC advisory. A couple of Air Force Reserve reconnaissance aircraft that have flew through the system early this afternoon reported dropsonde data that supported a minimum pressure of 998 mb and peak 850-mb flight-level winds of 42 kt. These data supported the upgrade of the system to Tropical Storm Sara on the 1800 UTC intermediate advisory. The latest Dvorak satellite intensity estimates from both SAB and TAFB also support 35 kt, therefore the initial intensity for this advisory is at that value. The forward speed of Sara is beginning to decrease as expected. The cyclone is now moving westward or 270 degrees at 9 kt. Sara should continue to move westward during the next couple of days to the south of a strong mid-level ridge, however a continued deceleration of Sara's forward speed is expected. By Sunday, the center of the ridge is forecast to move eastward over Florida which should cause Sara to turn west-northwestward when it approaches Belize and the southern portion of the Yucatan Peninsula. Most of the track guidance has nudged northward this cycle, and the NHC forecast has been adjusted accordingly. The new track continues to be along or just north of the coast of northern Honduras and it is in good agreement with the latest consensus aids. Environmental conditions are conducive for some strengthening during the next couple of days, but the main inhibiting factor is the sprawling structure of the cyclone and its close proximity to land. Given that the system is forecast to pass very close to the northern coast of Honduras, only modest strengthening is suggested by most of the guidance. The NHC intensity forecast calls for some strengthening during the next couple of days, follow by little change in intensity until the system moves over the Yucatan peninsula. It should be noted that a more northern track, could result in additional strengthening, but the global models and most of the intensity guidance does not favor that scenario. The global models indicate that the system will weakening quickly while it moves over the Yucatan peninsula and that the circulation is not likely to survive the passage over the peninsula. Therefore, the new forecast now calls for dissipation by day 5. KEY MESSAGES: 1. Through early next week, heavy rainfall from Sara will cause potentially catastrophic flash flooding and mudslides over portions of northern 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, and the adjacent Bay Islands where tropical storm warnings are in effect. 4. The system is forecast to approach Belize and the Yucatan Peninsula of Mexico late this weekend where there is a risk of strong winds. Residents in these areas should monitor the latest forecast updates.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * The northern coast of Honduras form Punta Sal eastward to the Honduras/Nicaragua Border * The Bay Islands of Honduras A Tropical Storm Watch is in effect for... * The northeastern coast of Nicaragua from Puerto Cabezas northward to the Honduras/Nicaragua Border A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in Honduras, Guatemala, Belize and 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 100 PM EST (1800 UTC), the center of Tropical Storm Sara was located by Air Force Reserve reconnaissance aircraft near latitude 15.7 North, longitude 82.9 West. The system is moving toward the west near 12 mph (19 km/h). This motion should continue through today, bringing the center near the coast of eastern Honduras. The system is expected to meander near the northern coast of Honduras late Friday and through the weekend. Data from the Air Force Reserve aircraft indicate that the maximum sustained winds have increased to near 40 mph (65 km/h) with higher gusts. Some strengthening is possible, if the system remains over water. Tropical-storm-force winds extend outward up to 70 miles (115 km) from the center, mainly in the northern semicircle. The estimated minimum central pressure based on dropsonde data is 999 mb (29.50 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 10 to 20 inches with isolated storm totals around 30 inches area 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, and western Nicaragua, 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 are expected in the warning area and possible in the watch area beginning later 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. NEXT ADVISORY ------------- Next complete advisory at 400 PM EST. $$ Forecaster Kelly

Tropical Depression Nineteen Forecast Discussion Number 4
2024-11-14 15:50:07| National Hurricane Center (Atlantic)
Issued at 1000 AM EST Thu Nov 14 2024 000 WTNT44 KNHC 141450 TCDAT4 Tropical Depression Nineteen Discussion Number 4 NWS National Hurricane Center Miami FL AL192024 1000 AM EST Thu Nov 14 2024 Latest satellite imagery depicts that the system continues to become better organized this morning, with improved curved banding features, and deep convection consolidating near the low-level center. The latest subjective intensity estimates were T/2.5 from both TAFB and SAB. The initial intensity is set to 30 kt, and an Air Force Hurricane Hunter aircraft is about to enter the system which will provide more information on current intensity and structure. The cyclone is moving westward with an estimated motion of 265/12 kt. A strong mid-level ridge located to the north of the system will continue steer the system westward towards Central America. The ridge is expected to break down, and the cyclone will meander in weak steering currents, Friday through the weekend. This expected slow motion will cause the system to produce heavy rains over the same region, likely causing life-threatening flooding over portions of Central America. By early next week, the mid-level ridge should slide eastward over Florida, which should cause the system to move northwestward across Belize and the Yucatan Peninsula. The NHC track forecast is in good agreement with the various consensus models, and is nudged slightly left towards the latest model trends. Environmental and oceanic conditions are conducive for some strengthening during the next day or so while the cyclone remains over water. There remains uncertainty in how much land interaction there will be with Honduras during the next several days, but the model trends have been southward showing more interaction. If the system remains along the coast or just offshore, it will likely maintain intensity or slightly strengthen. However, if the depression moves a little south of the forecast track, the system could be weaker than shown below. Given the slight leftward track adjustment with potentially more land interaction, the latest NHC intensity forecast is lower than the previous and is near the middle of the guidance envelope. However, it must be stressed that there is still a lot of uncertainty in the intensity forecast. KEY MESSAGES: 1. Through early next week, heavy rainfall will cause significant, life-threatening flash flooding and mudslides across portions of Central America, particularly Honduras, Belize, El Salvador, eastern Guatemala, and western Nicaragua. 2. Tropical storm conditions are expected along portions of the northern coast of Honduras, and the adjacent Bay Islands where tropical storm warnings are in effect. 3. The system is forecast to approach Belize and the Yucatan Peninsula of Mexico by early next week where there is a risk of strong winds. Residents in these areas should monitor the latest forecast updates. 4. It is too soon to determine what impacts, if any, the system could bring to portions of the eastern Gulf of Mexico, including Florida, during the middle portion of next week. Residents in these areas should regularly monitor updates to the forecast.
