Flood Watch
Issued: 6:02 PM Mar. 13, 2026 – National Weather Service
* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...The Big Island. * WHEN...Through late Sunday night. * IMPACTS...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... - Considerable flash flooding is possible beginning later today as a large and powerful kona storm northwest of the state draws deep tropical moisture northward across the islands.

You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. &&
