The National Weather Service has posted Flash Flood Emergencies for most of Southeast Texas, including Galveston and Harris Counties with total rain amounts of 15-25 inches possible by Thursday morning.

As if that weren’t bad enough, Tropical Storm Harvey may go into the record books not only as a catastrophic Category 4 on the middle Texas coast and a massive flood producer for much of coastal Texas, but also as one of the strangest storms ever to strike the Texas coast.

Harvey has begun an expected slow south-southeast drift and the official forecast track now places the system near the coast around Matagorda by very early Tuesday morning before heading back north.

However, some forecast models are suggesting that Harvey could move offshore and re-intensify (though nowhere near the Category 4 that pummeled Aransas Pass and Rockport). While this is only possibility and the official forecast track is not currently reflecting this, it is a reminder that we may have Harvey with us much longer than any of us would like,

In any case, pay attention to and heed statements from the Houston-Galveston NWS and emergency management personnel and limit travel to truly necessary jaunts. Also, be prepared for a prolonged period of heavy rain, high tides, tropical storm force wind gusts and isolated tornadoes.

Regardless of which model proves to be the most accurate, the result will be the same locally: windy, very wet weather with major flooding possible.
