Weather Summary

Weather Underground Forecast for Saturday, May 25, 2013.

Showers and thunderstorms will develop again across the Northern and Central Plains on Saturday as a low pressure system continues moving eastward across the center of the nation. The system will continue pulling moisture and energy northward from the Gulf of Mexico, bringing showers and thunderstorms to the region from the Northern High Plains into the Mid-Mississippi River Valley. There is a chance that these storms will turn severe across eastern Montana and western North and South Dakotas and western Nebraska. Large hail, damaging winds, and periods of heavy rainfall are likely in these areas, with possibly a few tornadoes. This system will move relativity slowly, thus, expect flooding concerns to increase over the region.

To the south, onshore flow will persist for Texas, maintaining showers and thunderstorms throughout the state on Saturday. Severe storms are not anticipated, but heavy rainfall and problems with flooding may persist for the region. In the East, showery weather will continue for the Northeast on Saturday as a low pressure system lingers over the region. Strong and gusty winds will also continue as this system slowly moves offshore. Out West, another disturbance brings more rain to Washington and Oregon Saturday night into Sunday. High pressure dominating across California and the Desert Southwest will keep most of this moisture away to the north. Thus, expect another sunny and dry day for the rest of the West Coast.

Flash Flood Watch
Mobile & Email Alerts Statement as of 4:05 AM AST on May 25, 2013

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

The Flash Flood Watch continues for

* all of Puerto Rico and the U.S. Virgin Islands.

* Through this afternoon

* showers and thunderstorms today will pose a risk of localized
heavy rainfall and isolated flash flooding. Deeper moisture is
being drawn over the area on east southeast low level winds and
will begin to interact with an upper level trough approaching
from the west. Widespread areas of two to four inches of rain
appear likely north of the central Cordillera... and eastern
Puerto Rico... with one to two inches possible over Culebra and
Vieques and the U.S. Virgin Islands. These amounts of rain could
fall in a short period of time leading to flash flooding of
small streams and rivers.

* Expect rapid rises in small streams or guts and rivers... with
mudslides possible in steep terrain.

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.
