Another round of activity may develop late tonight into early tomorrow morning.

Region 1 Tuesday, October 31, 2017Region 1

Elevated Conditions for the northwestern Gulf of Mexico Late Tuesday into Wednesday
A weak area of low pressure is forecast to build across the western Gulf of Mexico throughout the day on Tuesday. Southerly to southwesterly winds of 25-30 knots with gusts in excess of 35 knots are expected through Wednesday afternoon. With increased southerly winds to the south and southeast of the area of low pressure, seas of 7-9 feet are forecast through Wednesday afternoon. Strong thunderstorms with locally enhanced winds and seas are forecast to the east of the area of low pressure. 

Region 2 Tuesday, October 31, 2017Region 2

Thunderstorms for Portions on Wednesday of Texas and Louisiana
Showers will likely be ongoing during the morning hours across the Arklatex region. This will continue as a weak area of low pressure lifts northeastward along a stationary front. Gulf moisture and daytime heating should yield areas of instability, which may allow for a few storms to become marginally severe during the afternoon. Severe winds and a few tornadoes will be the primary hazards.
