Blink and you miss it. Tropical Storm Hermine made landfall yesterday in extreme northeastern Mexico as a strong tropical storm, with 65 MPH winds. If you went to bed early on Sunday night, you would have had no idea what the hell was going on Monday morning.
For a few days, the National Hurricane Center had an area of disturbed weather over the southwestern Gulf of Mexico highlighted as an area with a low chance for development into a tropical cyclone. During the day on Sunday, the NHC upgraded the area to a medium, then high, chance for development. By 11PM, the first advisory was issued, making the system Tropical Depression Ten. Within a matter of 16 hours, the storm would grow from a 30 MPH Depression to a 65 MPH Tropical Storm, bearing down on Northeastern Mexico and Southern Texas.
Hermine shows you what the right conditions can do to a system -- grow it from just a patch of thunderstorms to a strong tropical storm in under 24 hours. The whole time I watched Hermine, I couldn't help but think of Humberto in 2007.
