... Flash Flood Watch remains in effect through this afternoon...

The Flash Flood Watch continues for

* The Big Island.

* an approaching upper-level disturbance will enhance the deep
moisture already in place. Slow- moving and persistent heavy
showers and thunderstorms will result in the threat of flash
flooding.
