Flash flooding caused by excessive rainfall is possible.
WHERE
All Hawaiian islands.
WHEN
From Wednesday morning through Friday afternoon.
IMPACTS
Significant flooding may occur due to excessive rainfall and 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
- Low pressure will develop west of the islands and draw abundant moisture northward as it strengthens during the next couple of days. This will bring potential for heavy rain and thunderstorms leading to flash flooding over all Hawaiian islands.
Recommendations
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.

WHAT...An episodic fountaining eruption is expected within the Kilauea summit caldera. The Hawaiian Volcano Observatory has indicated a potential eruption window extends through Wednesday, April 15th. Fountaining episodes typically last less than 12 hours but ash can remain in the air longer depending on wind and weather. IMPACTS...If an eruption occurs, varying levels of ash, Pele's hair, and other lightweight tephra may fall downwind of the eruption. Smaller particles can travel farther from the eruption site and may affect communities at greater distances. For the next several days, "downwind" will be to the north and northeast of the summit.
Recommendations
If you live downwind of the Kilauea summit, or plan to visit the summit area, stay informed about current volcanic activity and weather conditions. Be prepared to take precautions if needed, such as disconnecting water catchment systems. Follow all guidance from the National Park Service and the County of Hawaii. Be aware that road or park closures may occur. This statement will be issued daily and updated as needed.
