San Jacinto Severe Watches & Warnings NOAA Weather Radio

Areal Flood Watch
Statement as of 11:02 PM CDT on September 17, 2014

...Flood Watch remains in effect through 7pm CDT Thursday...

The Flood Watch continues for

* a portion of southeast Texas...including the following counties...Austin...Brazoria...Brazos...Burleson...Chambers... Colorado...Fort Bend...Galveston...Grimes...Harris...Houston... Jackson...Liberty...Madison...Matagorda...Montgomery...Polk... San Jacinto...Trinity...Walker...Waller...Washington and Wharton.

* Through Thursday evening

* a tropical air mass combined with an upper level disturbance will cause wide spread showers and thunderstorms. Some areas have already received 1 to 3 inches of rainfall the last couple of days which has saturated grounds. Some storms will be capable of rainrates of 2 inches an hour which could overwhelm drainage basins causing flooding. Storms will also be moving slowly and could move over areas that received heavy rainfall further adding to the flood threat. Area bayous may quickly respond with rapid rises. Overall the area could see another 1 to 3 inches of rain with isolated 5 to 6 inch amounts.

* Timing - heavy rainfall could begin as early as 5am to 7am CDT Thursday but most likely later in the morning between 8am and 10am CDT. Heavy rainfall threat should continue into the afternoon with most storms dissipating with the loss of day time heating in the evening.

* Most likely area for heavy rainfall will be from College Station to Houston. Areas north of this line are more likely to receive heavy rainfall but coastal areas cannot be ruled out due to the large amounts of tropical moisture for storms to develop.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding based on current forecasts.

You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Vehicles caught in rising water should be abandoned quickly. If your vehicle stalls...abandon it and seek higher ground immediately. Rapidly rising water may engulf your vehicle and its occupants and sweep them away. Move to higher ground.

Turn around...don't drown!
