1106 AM EDT Wed Oct 7 2026



.SYNOPSIS...Tropical Storm Isaias is near 22.4N 93.6W, or about

moving east-northeastward at 7 kt. Maximum sustained winds are 40

kt with gusts to 50 kt, and the minimum central pressure is 1000

sustained winds 50 kt gusts 60 kt, strengthen to a hurricane near

23.4N 90.8W Thu morning with maximum sustained winds 65 kt gusts 

80 kt, and continue to strengthen as it nears 24.6N 89.2W Thu
