Severe Weather Alert Descriptions

 Special Weather Statement  Statement as of 7:17 am CDT on September 25, 2014


        ... elevated tides possible through tonight...

Tide levels have increased to 1.0 to 1.5 feet above normal this
morning due to a prolonged easterly fetch. Water levels may rise
further as east winds will likely persist through the day. The
long easterly fetch has also produced long period swells that will
propagate toward the coast. This could further increase tidal
action and increase the risk for some minor beach erosion.

Below is a table with the next high tide and expected water level
at that time.


Site high water
                                 tide level

Morgans Point 850 am 2.3 feet
                                1113 PM 2.4 feet

Eagle Point 1013 PM 2.7 feet

Galveston Bay entrance 556 PM 3.2 feet

Freeport 527 PM 3.0 feet

Port O Connor 1016 PM 2.0 feet

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
357 PM CDT Tuesday Sep 30 2014 


Discussion... 
daytime heating has gotten scattered (slow moving) storms going 
in the SW areas and a few from Madisonville to Livingston 
northward. Winds becoming more southeasterly as expected and 75-77 
dewpoints south of the warm front nearly onshore. Storms should 
continue through late afternoon then dissipate. The moisture 
should increase along the coast this evening and expect skies to 
clear. This will set the stage for fog forming tonight and have 
added patchy/areas of fog to the forecast after midnight. Have 
some concerns that dense fog will be possible in the southwest 
where rains will help to saturate the low levels and up north 
where drier air aloft will allow for greater temperature falls. 
Evening shift will need to keep an eye on the T/dew point spreads and 
such as a dense fog advisory may be needed. 


Isolated to widely scattered showers and thunderstorms will be 
possible Wednesday beginning over the waters and expanding inland 
in the morning. Warmer temperatures should prevail as well with a 
good cumulus field. By Thursday morning the moisture deepens and 
stronger moisture transport extends from southeast Texas to OK (magnitudes in 
the top 1 percent along with elevated temperatures aloft) so 
storms once they overcome the weak cap will be in a more favorable 
environment with 1500-2700 cape and Li -4 to -7 though the shear 
profiles diminish by early evening when much better forcing 
arrives associated with the cold front. Have raised probability of precipitation with 
frontal passage to 60-70 with the passage. Then abruptly drop as strong cold air advection 
kicks in and dry air arrives Friday morning. Very pleasant weather 
on tap Friday afternoon through Sunday with dry air and decreasing 
winds.

&& 


Marine... 
light easterly winds should become more southerly tonight into 
Wednesday with low seas. Winds will increase Wednesday into Thursday 
as a cold front approaches the area. The stronger southerly 
winds may build seas slightly into Friday. The cold front should push 
off the coast Friday morning and shift winds to the north/northeast. 
Northeast winds increase beginning Friday night into 
Saturday with building seas. Caution flags will likely be needed for 
conditions behind the front and advisory conditions are possible 
Saturday across the far offshore waters.
