Flash Flood Warning Issued Through the Afternoon
1:01 PM HST Friday, Feb. 19, 2021: National Weather Service in Honolulu
A Flash Flood Warning has been issued for the entire island of Kaua‘i until 4 p.m.
At 12:58 p.m., radar indicated heavy rain repeatedly forming over the mountains of Kaua‘i, with additional heavy showers and thunderstorms moving in from the east and southeast. Several inches of rain have fallen in the last couple of hours, and already elevated water levels in streams and rivers will rise, likely leading to the closure of Kūhiō Highway near Hanalei.
Impacted areas include flooding in drainages, streams, rivers, roads, properties, and other low-lying areas. Public road closures possible in some areas. Landslides are possible in steep terrain.
Stay away from streams, rivers, drainage ditches, and culverts, even if they are currently dry. Do not cross fast flowing or rising water in your vehicle, or on foot. Turn around, don’t drown.
This warning may need to be extended beyond 4 p.m. if flooding persists.
This Flash Flood Warning replaces the previously issued Flood Advisory that was in effect for The island of Kaua‘i in Kaua‘i County.
