Overview
As of this update, Ida has been downgraded to a Tropical Storm, but nonetheless is continuing to cause extensive weather constraints, equipment outages and some airport issues throughout Louisiana, Alabama and Mississippi. The center of the storm is located about 65 miles south/southwest of Jackson, MS, with maximum sustained winds of 45 mph. The storm is expected to pick up a little momentum and move northward later today on a track that splits the MEM and HSV terminals and eventually BNA by Tuesday morning.
Additional rapid weakening is forecast during the next day. The tropical remnants of Ida will meet a frontal system currently entering Indianapolis Center airspace later today and into Tuesday, bringing significant weather impacts including heavy rain, thunderstorms and possibly tornadoes – plus enroute constraints throughout northern ZME/ZTL and ZID.
Tropical storm warnings remain in effect from Grand Isle, LA, to the Alabama/Florida border, including metropolitan New Orleans and MSY airport.
Ida – Update from the National Hurricane Center
According to the National Hurricane Center’s Advisory #17, issued at 1200z:
At 700 AM CDT (1200 UTC), the center of Tropical Storm Ida was located by NOAA Doppler weather radars, satellite data, and surface observations near latitude 31.5 North, longitude 90.8 West. Ida is moving toward the north near 8 mph (13 km/h), and this general motion is forecast to continue today. A faster northeastward motion is expected to begin by tonight and continue on Tuesday. On the forecast track, the center of Ida will move farther inland over southwestern Mississippi this morning. Ida is then forecast to move over central and northeastern Mississippi this afternoon and tonight, and move across the Tennessee Valley on Tuesday.
Maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts. Additional rapid weakening is forecast during the next day or so, and Ida is expected to become a tropical depression this afternoon.
Tropical-storm-force winds extend outward up to 150 miles (240 km), mainly southeast of the center over water. A coastal marine observing site at Dauphin Island, Alabama, recently reported sustained winds of 38 mph (61 km/h) and a gust to 46 mph (74 km/h). A wind gust to 45 mph (72 km/h) was recently measured at Biloxi, Mississippi.
The estimated minimum central pressure is 993 mb (29.32 inches).
