Heavy rains drench Oahu, triggering flooding in some areas
HONOLULU (HawaiiNewsNow) - Heavy thundershowers moved over Oahu on Sunday night, triggering a flash flood warning as 2 to 3 inches of rain fell per hour in some communities.
Drenching rains triggered flooding in both directions on the H-1 Freeway in Honolulu. Rains on Sunday evening also reportedly triggered flooding on some roadways.
The National Weather Service warned that local stream levels were rising quickly Sunday night.
Flood advisories were also in effect for Oahu and Hawaii Island.
The severe weather was caused by an upper level disturbance over the islands.
Trade winds started making a return to the islands Monday morning. Forecasters said some isolated downpours may still be possible through Monday evening, while thunderstorms could still happen along upslope areas of the island of Hawaii.
Overall, the upper level disturbance is weakening, lowering the chance of severe weather conditions, with the return of drier trade wind weather by Thursday.
