DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Storm Pilar was located near latitude 11.3 North, longitude 90.9 West. Pilar is moving toward the east-northeast near 5 mph (7 km/h) and this general motion is expected to continue through Tuesday night. On the forecast track, Pilar could be near the coast of El Salvador or Nicaragua Tuesday through early Wednesday, though the core of the system is expected to remain offshore. The storm is forecast to begin moving west-southwestward away from land by late Wednesday. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Some strengthening is forecast, and Pilar could be near hurricane strength by late Tuesday. Weakening is expected to begin by late Wednesday and continue through Thursday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Pilar can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4 and WMO header WTPZ44 KNHC and on the web at hurricanes.gov/text/MIATCDEP4.shtml RAINFALL: Pilar is expected to produce storm total rainfall of 5 to 10 inches, with local amounts to 15 inches, over portions of Central America from El Salvador southward to Costa Rica through Wednesday. This rainfall will produce flash and urban flooding, along with mudslides in areas of higher terrain. SURF: Swells generated by Pilar are expected to continue affecting the Pacific coast of Central America during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. WIND: Tropical storm conditions could begin in the Tropical Storm Watch area Tuesday morning. NEXT ADVISORY ------------- Next intermediate advisory at 100 AM CDT. Next complete advisory at 400 AM CDT. $$ Forecaster Pasch NNNN
