A flash flood watch is up for all islands until 6 a.m. Monday.

There have already been numerous showers statewide and more rain is expected through the end of the weekend.

Some of the additional showers could be heavy and there may also be more thunderstorms.

All of that rain could lead to heavy runoff and create flash flooding.

While many of the showers are concentrated on the Windward coasts and mountain slopes, heavy rain could also take place in Leeward areas.
