Tropical Storm Sara Forecast Discussion Number 6

2024-11-15 03:55:18| National Hurricane Center (Atlantic)

Issued at 1000 PM EST Thu Nov 14 2024 404 WTNT44 KNHC 150255 TCDAT4 Tropical Storm Sara Discussion Number 6 NWS National Hurricane Center Miami FL AL192024 1000 PM EST Thu Nov 14 2024 Radar data from Belize shows heavy rainfall from Sara continues to spread over portions of Belize, the Yucatan Peninsula of Mexico, and Honduras tonight. There has been some increase in deep convection closer to the center of the storm this evening. A recent Air Force Hurricane Hunter flight leg over the northern semicircle found 925-mb flight-level winds up to 52 kt, which supports an initial intensity of 40 kt. The flight-level wind data also indicated that the center of Sara is likely just inland or very near the northeastern coast of Honduras, and the center was somewhat elongated west to east. Sara is moving westward (270/9 kt) to the south of a mid-level ridge centered over the Gulf of Mexico. A slower westward motion is expected over the next couple of days, with the center of Sara forecast to move along or very near the coast of northern Honduras. As the ridge slides eastward later this weekend, Sarah should turn toward the west-northwest by late Saturday and move across the Gulf of Honduras before approaching the coast of Belize on Sunday. The updated NHC track prediction is nudged slightly south in the short term, but generally lies between the latest simple and corrected consensus aids (TVCA/HCCA) with little overall change from the previous forecast. While the environmental and oceanic conditions are favorable for some intensification, Sara's relatively broad structure and proximity to land are likely to inhibit significant strengthening. Given the slight southward track adjustment, little intensity change is expected in the short term while the storm continues to interact with land along the northeastern coast of Honduras. Some further strengthening is forecast thereafter once Sara turns west-northwestward and moves over water. The updated NHC forecast shows a similar peak intensity as the previous prediction, in best agreement with the intensity consensus aids. Once again, a more northern track than forecast could result in additional strengthening. The storm is forecast to move inland over Belize on Sunday and quickly weaken while moving over the Yucatan Peninsula. This forecast shows dissipation by day 4, as the global models agree that the low-level circulation of Sara is unlikely to survive its trek across the Yucatan Peninsula. KEY MESSAGES: 1. Through early next week, heavy rainfall from 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, 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 from Punta Sal eastward to the Honduras/Nicaragua Border * The Bay Islands of Honduras A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. 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 1000 PM EST (0300 UTC), the center of Tropical Storm Sara was located near latitude 15.8 North, longitude 84.5 West. Sara is moving toward the west near 10 mph (17 km/h). A westward motion at a slower forward speed is expected during the next couple of days. A slow west-northwestward motion is forecast by late Saturday. On the forecast track, the center of Sara will move close to the northern coast of Honduras through early Saturday, then approach the coast of Belize on Sunday. Data from the Air Force Hurricane Hunters indicate that maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Some further strengthening is possible during the next couple of days if the center of Sara remains offshore of the northern coast of Honduras. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure 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, western Nicaragua, and the Mexican State of Quintana Roo, 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 in Honduras during the next couple of days. 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 intermediate advisory at 100 AM EST. Next complete advisory at 400 AM EST. $$ Forecaster Reinhart
