Isaias is no longer a hurricane and no longer a National Hurricane Center problem. In Advisory 15, issued at 4 a.m. Central on Saturday, October 10, the hurricane center reclassified the system as Post-Tropical Cyclone Isaias and said it was its last public advisory on the storm.
The center of the system was about 25 miles south-southwest of Montgomery, Alabama, with maximum sustained winds near 35 mph, moving north at 14 mph, with a minimum central pressure of 1002 millibars. All storm surge and tropical storm warnings were discontinued with that advisory, and the hurricane center listed no watches or warnings in effect anywhere. Isaias is forecast to cross Alabama into the Tennessee Valley through Sunday and to dissipate.
What is left of the storm, and where
The remaining hazard is rain, and it is well east of Texas. The hurricane center forecast 4 to 8 inches across southern Alabama, the Florida Panhandle and Big Bend, and southwest Georgia, with localized totals up to 15 inches, and 2 to 5 inches across much of the rest of the Southeast. It flagged flash, urban and river flooding as possible across that region, considerable flash flooding and landslides as possible in the southern Appalachians, and a continuing tornado risk across parts of the eastern Florida Panhandle, Georgia and the Carolinas.
Swells from Isaias are still expected to affect Gulf coastlines through the weekend and to cause dangerous surf and rip currents. That is the one piece of this system that still touches the Texas coast.
What it means here
Nothing, at this point, and that is the news. The Lake Houston area never came under a watch or warning from Isaias, the Kingwood forecast is sunny and dry through Sunday, and the Lake Houston gauge has moved about two tenths of a foot in the last 48 hours. Future updates on the remnants will come from the National Weather Service Weather Prediction Center rather than the hurricane center.
