Weather Summary

Weather Underground midday recap for Friday, May 24, 2013.

Heavy rainfall and strong thunderstorms developed over southern Texas and northern Mexico on Friday, as onshore flow from the Gulf of Mexico maintained warm and humid conditions. Rainfall totals reached over 2 inches by mid-day for the region. Uvalde, Texas saw a mid-day total of 2.06 inches of rain. Wind gusts up to 50 mph also accompanied this system.

To the north, showers and thunderstorms developed over the Plains as a broad low pressure system moved off the Rockies and into the Plains. This pushed a warm front eastward, which allowed for showers and thunderstorms to pop up from North Dakota through Kansas. These storms have not yet turned severe but there was a slight chance of severe thunderstorm development across northeastern Colorado and into western Kansas and Nebraska. Large hail and strong winds were likely in these areas, with possibly a tornado or two.

Meanwhile in the East, a trough of low pressure and associated cold front allowed for showers and thunderstorms to persist from the Mid-Atlantic states through Maine. Strong winds and heavy rainfall were reported from Pennsylvania through Maine. Out West, a trough of low pressure over the Pacific Northwest kicked up a few more scattered showers across Washington and Oregon, which moved into Idaho and western Montana.

Flash Flood Watch
Mobile & Email Alerts Statement as of 3:14 PM AST on May 24, 2013

... Flash Flood Watch remains in effect through Saturday afternoon...

The Flash Flood Watch continues for

* a portion of Puerto Rico... including the following areas...
central interior... Culebra... eastern interior... Mayaguez and
vicinity... north Central... Northeast... northwest... Ponce and
vicinity... San Juan and vicinity... southeast... southwest...
Vieques and western interior.

* Through Saturday afternoon

* scattered showers and thunderstorms this afternoon may pose a
risk of localized heavy rainfall and isolated flash flooding.
However... main threat for widespread heavy rainfall and greater
risk of flash flooding is expected to be tomorrow as deeper
moisture is drawn northwestward on east southeast low level
winds and begins to interact with an upper level trough
approaching from the west. Widespread two to four inches of rain
appear likely north of the central Cordillera... eastern Puerto
Rico... Culebra and Vieques. These amounts of rain could fall in
a short period of time leading to flash flooding of small
streams and rivers.


Precautionary/preparedness actions...

A Flash Flood Watch means that conditions are favorable for heavy
rain across the watch area... which may lead to flooding. If you are
in the watch area... check your preparedness requirements...
especially if you have interests along area rivers. Keep informed...
and be ready for quick action if flooding is observed or if a Flash
Flood Warning is issued.

People in the watch area should continue to be aware of the
possibility for heavy rainfall. Avoid low lying areas... and be
careful when approaching Highway dips and underpasses. The heavy
rain could also cause mudslides in areas of steep terrain.

Stay tuned to NOAA Weather Radio... local TV... radio or your cable
television provider for later statements and possible warnings.

This product... along with other weather... hydrological and climate
information... is available on the web at http://www.Srh.NOAA.Gov/sju
