HOUSTON - Just days after Houston was battered with rain and even a few tornadoes, Mother Nature is ramping up another round and aiming it right at southeast Texas.

"Tornadoes, hail, flooding, damaging winds, street flooding, heavy rain, that's a lot for us to have in one day," said Francisco Sanchez, with Harris County's Office of Emergency Management.

For the second time in a week, Houston's on severe weather watch and emergency management officials are getting ready.

Houston Police and Houston Fire are on alert.

Rescue vehicles are on standby in case they're needed after storms move in. Some areas could see 2-3 inches of rain in an hour, but where remains uncertain.

"We don't know where that's going to be, so someone watching this newscast will get the worst of it, but most people will not," said Sanchez.

That amount of rain in such a short time will cause street flooding, but Harris County's Flood District says the bayous should be fine. The County is set to activate the Emergency Operations Center at 7 a.m. Sunday.

"It will be a day-long event and people need to be prepared," said Jeff Lindner, with HCFD.  "Make sure those cell phones are turned on and able to receive those warnings tomorrow."
