Flash Flood Watch


Effective: Friday, October 12, 2018 - 6:00am to Saturday, October 13, 2018 - 6:00am

...FLASH FLOOD WATCH NOW IN EFFECT THROUGH LATE TONIGHT... The Flash Flood Watch is now in effect for

* Kauai and Niihau.

* Through late tonight

* Deep tropical moisture will spread northward over Kauai and Niihau today, with conditions becoming unstable as an upper level trough approaches from the west. This is expected to lead to the development of showers and thunderstorms across the western islands this afternoon. Light winds over the area will be supportive of slow moving showers and storms, which could lead to heavy rainfall and flash flooding. The most likely time frame for the heavy rainfall and potential flooding appears to be this afternoon into early this evening.
Notes (optional):

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

Warning Instruction:
A Flash Flood Watch means that conditions are favorable for flash flooding. Flash flooding is LIFE THREATENING. Do not cross fast flowing water in your vehicle or on foot. Monitor later forecasts and be prepared to take action if a Flash Flood Warning is issued. If you experience heavy rain or rising water, head to higher ground immediately.

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.
