... Flash Flood Watch now in effect through Sunday afternoon...

The Flash Flood Watch is now in effect for

* Through Sunday afternoon

* a front will stall over the area at the same time a potent low
aloft moves overhead, bringing slow-moving heavy showers and
thunderstorms that could result in flash-flooding. While

flooding will occur over Maui County, Oahu and The Big Island
also have the potential to receive flooding rain.

* Heavy rain is expected to be widespread, especially in Maui
County this weekend. Rain will affect windward areas, while
also impacting urban and leeward areas, which are more
susceptible to flooding problems, especially in south and west
Maui. These areas include Kihei, Lahaina, Kaanapali, and low-
water crossings along piilani Highway between Kaupo and
Ulupalakua.

212 PM HST Fri Apr 28 2017

The National Weather Service in Honolulu has issued a

* flood advisory for...
the island of Oahu in Honolulu County

* until 500 PM HST

* at 210 PM HST, radar indicated areas of very heavy rain developing
along a large portion of the southern half of Oahu, including
urban Honolulu, and the h-1 freeway between Fort Shafter and
Waipahu. Other showers were falling over the windward side near
Kaneohe. The heavier showers were dropping rain at a rate near two
inches per hour, resulting in very low visibility.

* Locations in the advisory include but are not limited to...
Honolulu, Waimanalo, Hawaii Kai, Ahuimanu, Pearl City, Salt Lake
Waikele, Kapolei, Kalihi, Manoa, Waipahu and Aiea.

Precautionary/preparedness actions...

Stay away from streams, drainage ditches and low lying areas prone to
flooding.

Rainfall and runoff will also cause hazardous driving conditions due
to ponding, reduced visibility and poor braking action.

Do not cross fast flowing or rising water in your vehicle, or on
foot. Turn around, don't drown.


This advisory replaces the previously issued advisory that was in
effect for portions of the island of Oahu in Honolulu County.

This advisory may need to be extended beyond 500 PM HST if heavy rain
persists.
