Southeast Gulf of America .SYNOPSIS...Weak high pressure has shifted into the N-central Gulf overnight, and extends a narrow ridge southeastward to the Yucatan Channel. The high pressure will drift slowly W-NW and settle across the NW Gulf through Thu. A 1014 mb low pressure is just offshore of central Florida near 29N79.5W and is forecast to move westward across Florida later today and tonight, and eventually emerge over the northeastern Gulf late Tue or early Wed. Environmental conditions appear generally favorable for additional development, and a tropical depression could form by the middle to latter part of this week as this system moves across the northeastern and north-central Gulf. Regardless, scattered to numerous showers and thunderstorms, some with strong gusty winds, will accompany this system. .TODAY...NW to N winds 5 to 10 kt. Seas 2 ft or less. Scattered tstms. .TONIGHT...N winds 5 to 10 kt, shifting to SE after midnight. Seas 2 ft or less. Scattered tstms. .WED...S winds 10 to 15 kt. Seas 3 ft.

The low is expected to move westward across Florida later today through tonight, and eventually emerge over the northeastern Gulf of America by late tonight or early Wed. Environmental conditions appear favorable and some development of this system is possible today before it moves over the Florida Peninsula. High pressure over the central Atlantic will then build westward across the region and across Florida late tonight through Sat in the wake of the low pressure. Active thunderstorms are expected in association with this system over the waters west of 76W through tonight. The pressure gradient between the Atlantic ridge building westward and the low pressure will support moderate to fresh SE to S winds across the Bahamas and through the NW zones today through early Thu. .TODAY...SE to S winds 5 to 10 kt S of 27N, and SE to S 15 to 20 kt N of 27N.
