Weather hell in Texas, the Gulf states

Harvey will drive 30,000 to shelters, FEMA says

Tropical Storm Harvey, now spinning near Port O'Connor, Texas, is forecast to move back into the Gulf of Mexico today, the National Hurricane Center said. 

It will meander over the Gulf for a couple of days before making a second landfall somewhere near the Texas/Louisiana border, likely on Wednesday.

Harvey is then expected to slowly move northeast across Louisiana and Arkansas as a tropical depression from Thursday into Saturday.

As it spins offshore, the storm is expected to dump an additional 15 to 25 inches of rain through Friday over the upper Texas coast and into southwestern Louisiana, exacerbating the life-threatening, catastrophic flooding in the Houston area, the hurricane center said. 

Isolated storm totals may reach 50 inches over the upper Texas coast, including the Houston/Galveston metropolitan area.

"Reliable weather forecasts still show taking whatever rain has already fallen around Houston and doubling it over the next 4-5 days," said WeatherBell meteorologist Ryan Maue.
