HOUSTON — Anyone who knows Houston KNOWS floods are part of life here. Yep, Houston is comparable to the tropical islands of the Pacific Ocean!

So what about tonight? We want to stay ahead of it in case it does happen. Street flooding is likely in spots before daybreak tomorrow.

Some areas could see 6 to 10 inches of rain, though most will get 2 to 5 inches and a flash flood watch continues for the Greater Houston Area.

How it's happening: A cold air mass is currently being forced into a warm, tropical, soupy lot of southerlies being pulled out of the Caribbean Sea. A storm system in the upper levels of the atmosphere in west Texas will forcing air to rise and result in the inevitability of heavy rain for at least several hours.

Doesn't sound like much? Well you're right that Houston's certainly seen much worse, but this time of year when the ground is cold, the grass has gone dormant and water simply can't absorb as quickly into the ground as it does in summer. This adds to excessive runoff and can send roads into a "no go zone" in a matter of minutes.

We are hoping this is nothing more than a rainy, windy soaker of a night. That said, if and when flooding does begin, I don't expect it to flood homes (and this is no Harvey!) so I'd simply advise to stay off the roads tonight. If you happen to live in an apartment complex that's known to flood, I can't guarantee that parking garages or even the first floor may not be tested.

Unfortunately, I do see the highest rainfall totals favoring the Houston metro instead of areas farther north due to the orientation of the temperature contrast. This is bad because the impervious surfaces of our city (roads, parking lots, etc) will only make the runoff process worse. Be safe tonight and never try to drive through flood waters -- especially at night.
