DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM EDT (0300 UTC), the center of Tropical Storm Julia was located near latitude 30.3 North, longitude 81.6 West. Julia is moving toward the north-northwest near 9 mph (15 km/h) and this motion is expected to continue tonight with a reduction in forward speed tomorrow. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some weakening is forecast during the next 48 hours. Little change in strength is expected tonight. Julia is forecast to weaken to a tropical depression by late Wednesday. Tropical-storm-force winds extend outward up to 45 miles (75 km), mainly to the northeast and southeast of the center. Recent observations indicate that sustained tropical-storm-force winds are occurring along the northeast coast of Florida from Ponte Vedra northward to the mouth of the St. Johns River. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical-storm-force winds are already occuring within the tropical storm warning area. RAINFALL: Julia is expected to produce 3 to 6 inches of rain near the northeast Florida, Georgia, and South Carolina coastlines through Friday afternoon. Isolated totals of 10 inches are possible. This rainfall could lead to flash flooding. Flooding may be further compounded with persistent strong onshore flow reducing river and stream discharges. TORNADOES: An isolated tornado or two will be possible tonight through Wednesday morning across parts of northeastern Florida and southeastern Georgia. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Stewart/Franklin NNNN
