hawaii_state_radar-935am-dec-3

A flash flood watch is in effect for all islands through Sunday afternoon.

The threat of heavy rain lasts through Monday with slight chance of thunderstorms for all islands. If you thought Friday was bad, it could get even worse, especially on Sunday, and southerly winds could bring in higher vog levels. Regular conditions are expected to return by Tuesday, then another bout of wet weather is expected Wednesday and Thursday, but likely not as severe.

Rainfall rates from heavier downpours and thunderstorms could cause streams to quickly overflow their banks leading to flash flooding.

Precautionary/preparedness actions:

  • A flash flood watch means that conditions may develop that lead to flash flooding. flash flooding is very dangerous.
  • You should monitor later forecasts and be prepared to take action should flash flood warnings be issued. Campers and hikers should consider postponing their outing until the weather is better. High streams as well as streams overflowing their banks could make conditions very dangerous.

Brown Water Advisory

A Brown Water Advisory is being issued from Nawiliwili to Hanalei Bay due to heavy rains. The public is advised to stay out of flood waters and storm water runoff due to possible overflowing cesspools, sewer manholes, pesticides, animal fecal matter, dead animals, pathogens, chemicals, and associated flood debris. Not all waters may be affected, however if the water is brown stay out and continue to practice good personal hygiene. Follow up with your primary care physician if you have any health concerns.

School Closure

Staff at Hauula Elementary say the stream near the school flooded, and water spread to much of the campus. Students were sent home early while staff scrambled to place sandbags to protect buildings. The school was officially closed at 11:30 a.m.
