Severe Weather Alert Descriptions

 Areal Flood Advisory  Statement as of 4:21 am CDT on August 1, 2014


The National Weather Service in League City has issued a

* Urban and Small Stream Flood Advisory for...
Harris County in southeast Texas...
east central Fort Bend County in southeast Texas...
Brazoria County in southeast Texas...
Galveston County in southeast Texas...

* until 515 am CDT

* at 416 am CDT... Doppler radar indicated heavy rain from slow
moving clusters of rain and thunderstorms that will cause Urban
and Small Stream flooding within the advisory area. 1 to greater
than two inches of rain has already fallen over southern Fort Bend
and into northern Brazoria counties.

* Some locations that may experience flooding include...
Pasadena... Pearland... League City... Baytown... southeastern
Missouri City... Galveston Island west end... Galveston Island east
end... Galveston causeway... Texas City... Friendswood... La
Porte... Deer Park... Lake Jackson... Alvin... Angleton... Dickinson... South
Houston... Bellaire... West University Place and La Marque.

Additional rainfall of 1 to 2 inches is expected over the area. This
additional rain will cause the minor flooding of roadways and low lying
areas.

Precautionary/preparedness actions...

Most flood deaths occur in automobiles. Never drive your vehicle into
areas where the water covers the roadway. Flood waters are usually
deeper than they appear. Just one foot of flowing water is powerful
enough to sweep vehicles off the Road. When encountering flooded
roads make the smart choice... turn around... dont drown.

Excessive runoff from heavy rainfall will cause ponding of water in
urban areas... highways... streets and underpasses as well as other
poor drainage areas and low lying spots. Do not attempt to travel
across flooded roads. Find alternate routes. It takes only a few
inches of swiftly flowing water to carry vehicles away.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams... as well as farm and country roads. Do not
attempt to travel across flooded roads. Find alternate routes.

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. Move to higher ground.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
358 am CDT Friday Aug 1 2014 


Discussion... 
showers/thunderstorms with very heavy and flooding rainfall in/around 
the Houston metropolitan area continue to gradually work their way southward 
towards portions of our coastal counties as a weak cold front slowly 
works its way across the area. Rainfall with earlier storms across Harris 
County (via the county's Flood Warning system) included 5.68 inches 
in 1 1/2 hours on Greens Bayou at Highway 59...a 6.56 inch total at 
Aldine Westfield...and a 5.40 inch total at I-45 and west Road. At one 
point...hourly rates were as high as 4 to 5 inches along the beltway 
8 and Highway 59 area. Currently...storm mergers along with high precipitable 
water values support the threat for more locally heavy rainfall and 
possible flooding through sunrise mainly between Highway 59 and the 
coast. With the front moving slowly across the area during the day 
today...any daytime heating and recovery from the overnight storms 
would support additional shower and thunderstorm development. The 
weak front is expected to meander back and forth across the area over 
the weekend...so will continue to keep rain in the forecast with the 
lower chances northwest and the higher values near the coast. Next 
week's weather is going to depend on the strength/location of upper 
level ridging centered to our west. Portions of our area look to be 
on the eastern edge of the ridge which should allow for some mainly 
daytime shower/thunderstorm development. 42 
&& 


Marine... 
an approaching weak cold front will hang up near the coast today. 
This near stationary boundary will serve as a focus for return 
showers and thunderstorms through the weekend. Except within or in 
the vicinity of maritime storms where winds and seas could quickly 
become dangerous...general onshore winds will be light and seas 
will be very low at or under two feet. 31
