HOUSTON — A Flash Flood Warning has been issued for Harris and Montgomery counties until 3:30 a.m. and street flooding is possible.

Both counties are also under a Severe Thunderstorm Warning until 2:15 a.m.

There’s also a Flash Flood Warning in effect for Liberty and Polk Counties until 2:15 a.m.

Multiple Tornado Warnings were issued early Saturday evening and again late Saturday night as storms rumbled north-by-northeast across the Houston area. They have now expired.

Radar confirmed two tornadoes touched down — in the Humble area and Liberty County — according to KHOU 11 Meteorologist Tim Pandajis. There are reports of some damage in Montgomery County.

If you’re in the path of a tornado, you should seek shelter in an interior room, take cover and stay away from doors and windows.

WATCH: Sunday forecast

• Sunday: A few overnight storms could produce about an inch of rain. The more active severe threat moves in between 2:30 and 6:30 a.m. After that, the overall trend for Sunday will be less rain as a new cold front moves through. The rain should move offshore by 2 p.m.

A few spotty showers could linger in the Houston Metro for the Texans tailgate. What else will linger? The warmth! Temps hover in the mid 70s most afternoon. The record stands at 80 degrees so likely in the clear but still not very winter-like temps.
