HOUSTON -

Severe weather rolled through the Houston area for the third straight day.

Early Wednesday morning, lightning and heavy rain pummeled parts of Harris and Montgomery counties. 

Local 2 Meteorologist Anthony Yanez says there have been thousands of lightning strikes overnight, and hundreds in the last few hours. 

Scattered showers and thunderstorms are expected Wednesday afternoon, the NWS says, and the storms should be fast-moving.

Because the ground is so saturated from the past three days and more rain is expected, a Flash Flood Watch for most of Southeast Texas has been extended until 8 p.m. Wednesday.

Water levels are high in bayous and creeks throughout Harris County, and widespread street flooding has occurred, according to the Harris County Flood Control District.

HCFCD says the South Mayde Creek, Little Cypress Creek, Cypress Creek and Willow Creek are near or out of their banks. The National Weather Service says the San Jacinto River near Kingwood is right at flood stage.

Even though the rain is gone, that doesn't mean the threat is over as water starts to pool and pond on certain roads.
