A watch has been issued for the Platte, Elkhorn, and Loup rivers
due to potential ice jam development. This heightened threat is due
to persistent warm weather. Those with interests along area rivers,
especially in low-lying areas, should remain vigilant to the
potential for rapidly rising water.

* WHAT...Flooding caused by an ice jam continues to be possible.

* WHERE...Portions of east central, northeast, and southeast
Nebraska, including the following counties, in east central
Nebraska, Butler, Dodge, Douglas, Sarpy, Saunders and Washington.
In northeast Nebraska, Antelope, Colfax, Cuming, Madison, Pierce,
Platte and Stanton. In southeast Nebraska, Cass.

* WHEN...Through Monday evening.

* IMPACTS...The formation of an ice jam could result in sudden rises
of water, leading to a rapid flooding situation. Ice jams can
cause water level fluctuations of 1 to 3 feet over a very short
time period and without much notice.

* ADDITIONAL DETAILS...
- While no ice movement has been observed or reported, several
consecutive days of highs ranging from the upper 40s to mid
60s suggest breakup and movement is imminent.

...PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

Kauai County, HI Honolulu County, HI Maui County, HI Hawaii County, HI

...FLOOD WATCH IN EFFECT FOR ALL HAWAIIAN ISLANDS FROM SATURDAY
AFTERNOON THROUGH MONDAY AFTERNOON...

* WHAT...Flash flooding caused by excessive rainfall is possible.

* WHERE...All the main Hawaiian islands.

* WHEN...From Saturday afternoon through Monday afternoon.

* IMPACTS...Flood prone roads and other low lying areas may be
closed due to elevated runoff and overflowing streams. Urban areas
may receive more significant flooding and property damage due to
rapid runoff.

* ADDITIONAL DETAILS...
- A front will move southeast into Kauai late this afternoon,
then through Oahu and into Maui County tonight. The front
will stall over Maui County this weekend, allowing deep
tropical moisture to pool over the island chain. This in
combination with a disturbance aloft moving over the state,
will bring the potential for heavy rainfall, a few
thunderstorms and flash flooding beginning Saturday afternoon
and continuing through Monday afternoon. The greatest risk
for flash flooding is expected in windward areas.

...PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
