Flash Flood Watch

*** START NOTIFICATION ***

Effective: Thursday, April 19, 2018 - 6:00am to Friday, April 20, 2018 - 6:00pm

Alert:
...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH FRIDAY AFTERNOON... The Flash Flood Watch continues for

* The entire state of Hawaii.

* Through 6 PM Friday.

* The remnants of an old front lingering across the state in combination with an upper level trough moving overhead, will bring the threat for heavy rainfall and flash flooding. The heaviest rainfall is expected to fall from Oahu eastward to the Big Island, particularly in windward areas. Even though widespread heavy rainfall is not expected on Kauai, given the high levels of saturation from recent rainfall, any additional moderate rain falling for an extended period of time could quickly result in flooding problems.

* Rapidly rising water levels may occur on area streams and significant flooding may occur in low lying and poor drainage areas.
Description:

A Flash Flood Watch means heavy rain leading to flash flooding is possible.

Instruction:
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is very dangerous. Monitor the forecast and be prepared to take action if you see rising water or if Flash Flood Warnings are issued.

Unmonitored lands and waters in the impact area described in the alert will also be impacted.

If conditions change before expiration or the event needs to be extended, an update or cancellation will be issued from Hawaii Beach Safety Website.
