DISCUSSION AND OUTLOOK ---------------------- At 700 PM EST (0000 UTC), the center of Tropical Storm Sara was located near latitude 15.9 North, longitude 84.0 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 during the next couple of days and approach the coast of Belize on Sunday. Data from the Air Force Hurricane Hunters indicate that maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some 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, primarily to the north of the center. The estimated minimum central pressure based on aircraft data is 998 mb (29.47 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.

Tropical storm conditions are possible in the watch area in Nicaragua tonight. 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 1000 PM EST. $$ Forecaster Reinhart |
