Synopsis for the Gulf of America

442 PM EDT Thu Jul 23 2026



.SYNOPSIS...Tropical Storm Bertha is near 29.8N 94.7W at 5 PM 

EDT, and is moving west-northwest at 11 kt. Maximum sustained 

winds are 35 kt with gusts to 45 kt, and the minimum central 

pressure is 1006 mb. Bertha will move inland and weaken to a 

tropical depression near 29.7N 97.2W Fri morning, and dissipate 

Fri afternoon. In the wake of Bertha, a high pressure center will 

become established over the NE Gulf through Fri, then shift to the

central Gulf. The high pressure will provide for a light to 

gentle wind flow across the basin, except for pulsing moderate to 

fresh winds off the Yucatan Peninsula and near NE Mexico and the 

Texas coast through the weekend.
