SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. Interests in the southeastern United States should monitor the progress of Irma. Discussion AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM EDT (0300 UTC), the center of Tropical Depression Irma was located near latitude 32.4 North, longitude 84.9 West. The depression is moving toward the northwest near 15 mph (24 km/h), and this motion at a slightly slower speed is expected through Tuesday. A turn toward the north-northwest is forecast Tuesday night. On the forecast track, the center of Irma will move into Alabama soon and then into western Tennessee by Tuesday evening. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is forecast, and Irma is expected to degenerate into a remnant low by Tuesday evening. The low is likely to dissipate by Wednesday evening. The estimated minimum central pressure is 988 mb (29.18 inches). HAZARDS AFFECTING LAND ---------------------- Storm SURGE: Water levels are gradually subsiding along the southeastern United States coast and the west coast of Florida. WIND: Gusty winds to tropical storm force are possible near the coast of South Carolina and in heavier rainbands across the southeastern United States overnight. RAINFALL: Irma is expected to produce rain accumulations of 2 to 5 inches with isolated 8 inches through Wednesday across South Carolina and northern portions of Georgia, Alabama, and Mississippi into Tennessee and North Carolina. SURF: Swells generated by Irma are affecting the southeast coast of the United States. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system.
