Weather Summary

Weather Underground Forecast for Friday, May 24, 2013.

Showers and thunderstorms will move into the Plains, while also continuing across the East Coast on Friday. A low pressure system over the Rocky Mountains will persist on its eastward track and move into the Plains. Flow around this system will create northward flow, pulling abundant moisture and energy in from the Gulf of Mexico. This will allow for scattered showers and thunderstorms to develop across the Southern Plains again on Friday, spreading northward through the Central and Northern Plains. There is a slight chance that these storms will turn severe across northeastern Colorado, into western Kansas and Nebraska. Large hail and strong winds are likely in these areas, with possibly a tornado or two.

Meanwhile in the East, a trough of low pressure and associated cold front will slowly move eastward and offshore the East Coast on Friday. This system will allow for showers and thunderstorms to persist from the Mid-Atlantic states through Maine. Severe thunderstorms are not likely in these areas, but periods of heavy rainfall and strong winds will persist as this system lingers over the Northeast through Friday night.

Out West, an area of low pressure continues spinning over the Pacific Northwest, maintaining onshore flow. This will bring more rain showers to Oregon and Washington, with snow showers possible at highest elevations.

Flash Flood Watch
Mobile & Email Alerts Statement as of 5:40 AM AST on May 24, 2013

... Flash Flood Watch in effect from noon AST today through Saturday
afternoon...

The National Weather Service in San Juan has issued a

* Flash Flood Watch for all of Puerto Rico... including Culebra and
Vieques.

* From noon AST today through Saturday afternoon

* a surge of moisture in the easterly trade winds will bring heavy
showers and scattered thunderstorms to the area. Some of these
areas will see repeated passages of heavy showers leading to flooding.

* Numerous showers and thunderstorms will raise some area small
streams and rivers to flood stage during the next 24 to 36
hours. Some roads and highways in the area will become
impassable... especially during the afternoons or early evening.

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
