Severe Weather Alert Descriptions

 Areal Flood Watch  Statement as of 10:51 am CDT on September 19, 2014


... Flood Watch now in effect until 7 PM CDT this evening...

The Flood Watch is now in effect for

* a portion of southeast Texas... including the following
counties... Austin... Brazoria... Chambers... Colorado... Fort
Bend... Galveston... Harris... Jackson... Liberty... Matagorda...
Montgomery... Waller and Wharton.

* Until 7 PM CDT this evening

* over the past few days the region has received copious amounts
of rain... an average 2 to 4 inches of rain with some isolated
areas picking upwards of 7 to 8 inches. Showers and storms
developed early this morning and had little to no movement.
Scattered to numerous showers and thunderstorms are expected to
redevelop later today... possibly further south as central County
morning activity sags towards the coast. The forecast is for
pockets of light to moderate rain to put down another 1 to 2
inches of rain... locally 2 to 4 inches... through tonight. The
potential for training rain will only exacerbate localized
flooding generally in and around the city of Houston and points
west and southwestward. This additional rainfall will likely
cause nuisance street flooding and low lying areas to go under
water. Motorists should avoid any flooded roadway.

South mayde creek in western Harris County is currently out of
banks. Residents that live near local bayous need to closely
monitor bayou water level behavior. Due to recent run-off
issues... a quick burst of excessive rainfall over these basins
will provide for rapid bayou water rises.

* Timing and location... precipitation is ongoing but slowly
weakening this morning. A late morning into early afternoon lull
is expected over the more populated areas of Harris... Montgomery... Fort
Bend... and Galveston counties with a re-generation expected by
mid to late afternoon. Primarily rain should be focused from
south of a Bellville to Conroe to Liberty line... .shifting
southerly though the day. Daytime heating will aid in
regenerating additional pockets of light to moderate rain or
showery weather... with very localized stronger cells quickly
producing 2 to 4 inch per hour rates.

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!

Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1214 PM CDT Friday Sep 19 2014 


Discussion... 
see 18z aviation discussion. 


&& 


Aviation... 
intense convection over Harris County will probably stabilize 
things over the Houston terminals this afternoon with convection 
redeveloping on the periphery of this mornings rainfall. Have 
removed thunderstorms and rain from khou/kiah/ksgr but will keep thunderstorms in the vicinity for other 
airports. Forecast soundings really dry things out overnight and hint 
at clearing skies after 06z. Feel residual moisture will allow for 
patchy fog and perhaps some MVFR/potentially LIFR ceilings toward 
sunrise. Drier weather is expected on Saturday with light east-southeast 
winds. 43 


&& 


Previous discussion... /issued 1125 am CDT Friday Sep 19 2014/ 


.Flood Watch is now in effect until 7 PM CDT this evening for 
the southern two thirds of the County Warning Area... 


Update... 
day three of the rain event is appearing to be much more tame 
than the previous two. The southern third of the forecast area is 
certainly not out of the Woods yet concerning the regeneration of 
afternoon convection that could lead to localized flooding but... 
overall...it does appear the heavy rain-leading-to-widespread-flooding 
threat is diminishing. Thus...have pared back the current Flood 
Watch to cover those counties that have received the highest rainfall 
over the past 24 hours and have shortened it's in effect duration. 


All of the met elements are still there for the afternoon regeneration 
of light to moderate rain...especially points west and south of the 
city of Houston. A moisture axis centered over the Texas coastline 
with a couple of areas of low-middle level convergence...along with 
better upper level diffulence than yesterday. Of course...the 
moisture values are still high but more centered from Galveston 
County and points offshore. The one feature that may not be a factor 
today (as in previous days) will be a strong enough upstream 
shortwave disturbance to aid in triggering lift. As is the case with 
tropical air masses...they do not as much warming/lift in generating 
precipitation so please reference the second sentence. There is an 
intrusion of drier northeasterly air that will significantly thwart 
the redevelopment of eastern region precipitation...it appears that 
any redevelopment will generally be along and south of the I-10 
corridor from today into the weekend. The flash Flood Advisory product GOES further 
into the quantitative precipitation forecast...timing... and location of near term rainfall. 31 


&& 


Previous discussion... /issued 452 am CDT Friday Sep 19 2014/ 


Discussion... 
showers and a few thunderstorms developed quickly around 330 am 
and have continued to expand and intensify. Storms are lining up 
from around College Station across Montgomery County and another 
line across Brenham to SW Harris to Galveston. These storms appear 
to be focusing along the 850-700 trough axis and moisture is in 
abundance with GPS data showing 2.4" precipitable water at Houston and model 
sounding are progging very favorable conditions for heavy rainfall 
across the area today. Have expanded the Flood Watch and extended 
it to 10 PM though by 7 PM am expecting storms to be weakening. 
Of note the Texas tech WRF ensemble paints a very wet pattern for 
much of the area from College Station to Huntsville and around the 
Houston metropolitan area. Do have some concerns that breaks in the 
clouds today could drive up temperature and dramatically increase 
the instability. Based on yesterdays minimal diuranal temperature 
ranges have lowered temperatures today and they may need further 
shrinking. 


As ridging settles into lower MS valley Saturday drier air first 
in the middle levels and eventually the lower levels spreads into the 
area from the east and rain chances shift southwestward and fall 
off dramatically from todays numbers. A shot of drier air pushes 
in with the next front and by midweek very pleasant weather should 
be on tap. 45 


Marine... 
onshore winds will remain relatively light over the waters today 
thanks to a weak pressure gradient. Winds will begin to back Sunday 
and turn easterly as the next weak cold font approaches. Weekend 
mariners can expect slightly elevated sea heights due to the 
prolonged easterly fetch. A secondary surge of upper level energy 
will push the cold front slightly further south on Monday but it 
will still not make it. East winds will persist through next weekend 
and gradually strengthen toward the end of the week as the pressure 
gradient tightens. A persistent easterly fetch will allow tide 
levels to slowly increase through the week. 23
