Flood Watch issued January 3 at 4:08AM HST until January 5 at 6:00PM HST by NWS Honolulu HI
...FLOOD WATCH FROM LATE TONIGHT THROUGH MONDAY AFTERNOON FOR ALL
HAWAIIAN ISLANDS...
* WHAT...Flash flooding caused by excessive rainfall continues to be
possible.
* WHERE...All the main Hawaiian islands.
* WHEN...From late tonight 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. Significant flooding may occur due to the overflow
of streams and drainages. Roads in several areas may be closed,
along with property damage in urban or low lying spots due to
runoff. Landslides may also occur in areas with steep terrain.
* ADDITIONAL DETAILS...
- A kona low will develop north of Kauai late tonight drifting
along a southwestward track on Sunday before drifting to the
west by Monday.
Deep unstable moisture will spread across all islands,
convective cloud bands riding in on southeasterly to
southerly winds will produce periods of moderate to heavy
showers and thunderstorms affecting all islands. For the Big
Island and Maui, the greatest flood risk remains along the
southeast slopes driven by strong southeasterly winds
building heavy showers over island mountains.
Lingering instability over some islands may extend the timing
of this Flood Watch into Tuesday.
You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
