The National Weather Service has informed the Department of Emergency Management that Oahu can expect an increase of strong storm activity overnight and into tomorrow.  Heavy rainfall and flooding, strong thunderstorm winds, hail and frequent periods of lightning are forecast with the peak effects occurring sometime Friday afternoon.

Although rainfall could be intense at times the bands of showers should move quickly over Oahu as the storm system tracks west of the state today thru Saturday.

Oahu is currently under a Flash Flood Watch thru Friday afternoon. A Flash Flood Watch means that conditions may develop quickly that could lead to flash flooding. Residents should be aware that it does not have to be raining heavily where they are for flash flooding to occur. Everyone should monitor TV and radio for the latest weather information and be prepared to take immediate action should the Flash Flood Watch be replaced with a Flash Flood Warning.
