Severe Weather Alert Descriptions

 Areal Flood Watch  Statement as of 2:38 PM CDT on September 18, 2014


... Flood Watch now in effect through Friday morning...

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... San Jacinto... Waller and Wharton.

* Through Friday morning

* rainfall within this tropical air mass has been excessive over
particular areas of the watch area. 48 hour rainfall totals are
greater than 5 inches over areas of western Harris... northern
Montgomery and southern San Jacinto counties... with the highest
6 hour totals just northwest of downtown Houston and along Clear
Creek. Area bayous may quickly respond with rapid rises within
rain exceeding four inch per hour rates. There is a good chance
that the area could see another 1 to 3 inches of rain with
isolated 3 to 4 inch amounts through Friday morning. Since this
is a tropical air mass... the flooding threat will come from slow
moving pockets of heavy rain or isolated thunderstorms... possibly
being enhanced by storm or outflow mergers.

* After this afternoon's activity wanes through late afternoon...
the timing of the next moderate to heavy rainfall is expected to
become more widespread early Friday morning and possibly continue
into the early afternoon.

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!

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
348 PM CDT Thursday Sep 18 2014 


Discussion... 
today's highest rainfall rates of near 5 inches per hour occurred 
over western and southern Harris...northern Galveston...northern 
Montgomery and southern San Jacinto counties. Of course...many 
low lying areas/streets quickly went under water as this rain 
fell on an already saturated / urban landscape. After about three 
plus hours of merging slow-moving training moderate/heavy rain 
(isolated thunderstorms) clusters...there will be a short lull 
across many of those areas. As these counties slowly drain and the 
atmosphere re-charges...there are numerous rain/storm cells gathering 
along a weak central Texas boundary and these will likely expand 
back towards the east and initiate a good round of northern County Warning Area 
rainfall through the late afternoon into middle evening hours. A 
shortwave disturbance diving down into central Texas will enhance 
this far interior activity. Near zero storm movement within this 
greater than 2.3 inch precipitable water air mass equates to various communities 
dealing with excessive rainfall into the overnight hours. Granted... 
those far northern counties from Brazos east over into Madison 
and Houston counties have not seen as much 24-48 rainfall and their 
upper level soil layers are not very saturated...but if the rain 
rates that occurred in Houston and surrounding counties occurs...then 
northern forecast area flooding will occur. This northern activity is forecast 
to slowly sag southward overnight and merge with re-developing southern 
forecast (+)ra clusters from as early as around Friday midnight and 
persist through the early afternoon. Needless to say...the Flood Watch 
as been extended. Buffalo bayou-downtown has recently come out of 
banks with run-off...a reminder that it is best to keep abreast 
of the latest Hydro products for future updates upon local bayou 
water level trends. 


Once this 'chapter' of precipitation comes to an end sometime late 
Friday into early Saturday morning...the next area to monitor for 
return rain will be closer to the coast and points southwestward. 
The recent better lower level convergence of offshore southeasterlies 
running into inland easterlies will turn more Uni-directional southeast. 
Still holding onto the idea that a weak backdoor front will move 
in from the Sabine and shunt the higher moisture towards the coastal 
Bend Saturday morning. Upper ridging is forecast to never really 
gain a real foothold over eastern Texas...with an unsettled near- 
coastal scenario unfolding within the nwp solutions. Generally lower 
heights and a vicinity offhsore inverted trough forming in the 
surface pressure field...along with random waves moving up from 
the far offhsore waters...all lean the forecast to low rain 
chances across the southern third of the County Warning Area through late Sunday. 
Southwestern U.S./Northern Mexico upper ridging is forecast to 
expand a bit further east to begin the next work week. This has 
rain chances falling to just slight near the coast...under slight 
inland. Monday through Friday rain chances will remain slight to 
low chance along the coast and Gulf through the remainder of the 
period based upon the unsettled nature of the gulf's overlying 
atmosphere...the 20 to 40 probability of precipitation isoplethes will migrate inland 
each day past middle-week due to interior warming into the upper 
80s...surpassing prognosticated low-middle 80f convective temperatures. 31 


&& 


Marine... 
low pressure over norther Mexico will produce a southeast wind 
tonight. High pressure to the north of Texas and weak low pressure 
over northern Mexico will allow an east wind to develop on Friday 
and persist through early next week. Weekend mariners can expect 
slightly elevated sea heights due to the prolonged easterly fetch. 
Winds should slowly decrease on Monday as the pressure gradient 
begins to relax. A cold front will approach southeast Texas on Tuesday but 
will probably stall north of the coastal waters. East winds will 
persist through Friday and gradually strengthen toward the end of 
the week as the pressure gradient. A persistent easterly fetch will 
allow tide levels to slowly increase through the week. 43
