Severe Weather Alert Descriptions

 Areal Flood Watch  Statement as of 6:07 am CDT on September 18, 2014


... Flood Watch remains in effect through this evening...

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 this 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 rainfall rates 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 expected to become more widespread late
this morning and continue into the afternoon. Storms should
dissipate by this evening with the loss of day time heating.

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 
455 am CDT Thursday Sep 18 2014 


Discussion... 
wet forecast to continue today but with a continued threat of flood- 
ing. Grounds wet from rains the previous few days along with the 
potential of additional rains today will keep the Flood Watch in 
place through this evening. 


Already seeing development over the nearshore waters this morning 
as the continued warm air advection flow collides with the more S/southeast moving dis- 
turbance coming out of south central Texas. Also seeing hints of yet 
another disturbance trying to dive down from North Texas. These system- 
tems combined with this still very moist/tropical airmass already 
in place should produce widespread convection across the County Warning Area through 
this aftn/eve. 


Per the latest model runs...the rest of the week/weekend forecast 
should see some drying but consensus not as strong with this next 
cold front early next week. Forecasts appear to be having issues with 
the handling of the remnants of Odile and may be exaggerating its 
impact on the main upper flow/pattern. As such will not be chang- 
ing the extended forecasts (too much) of frontal passage Monday (along with cooler 
and drier condtions next week). 41 


&& 


Marine... 
scattered showers and thunderstorms will continue this morning 
and may have a cluster move into the coastal waters this afternoon 
with gusty winds. Southeast winds will become more easterly on 
Friday...and increase Friday night and Saturday. Weak high 
pressure settles over southeast Texas/la and winds should slowly relax on 
Monday. A cold front should (if the European model (ecmwf) is correct-favoring it 
attm) move into the coastal waters on Tuesday of course depending 
on how well the models handle Odile and the next trough through 
the eastern U.S. 
45 


&& 


Aviation... 
have revamped the tafs this morning to swing the showers to the 
morning hours and the thunderstorms and rain to the late morning through afternoon. 
Soundings are very supportive of heavy downpours and with the 
radar/WV showing the next system NE to sjt and the short wave over shv 
arriving late this morning and afternoon. Will need to keep an eye 
on the system near San Antonio with the rain cooled air sagging 
south through the area. IFR/vlifr plaguing the northern terminals 
and concerned it may reach iah this morning for an hour. Expecting 
a break in rain showers/thunderstorms and rain coverage after 23z through 03-06z.
