... Flash Flood Watch in effect until midnight HST tonight...
The National Weather Service in Honolulu has issued a
* Flash Flood Watch for all Hawaiian islands
* until midnight HST tonight.
* A very moist air mass... together with a trough of low pressure
in the middle atmosphere overhead... has been encouraging locally
heavy showers and thunderstorms to develop during the night.
Although most of the heaviest precipitation remained offshore...
rainfall locally saturated the soil from Oahu to The Big Island
overnight. Showers and thunderstorms are expected to cover only
a portion of the state at any one time... but local impacts may
be significant... and training showers may permit heavy rain to
continue at individual locations for extended periods of time.
Shower and thunderstorm development is expected to increase in
the afternoon and early evening.
A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is very dangerous. Remember
that it does not have to be raining heavily where you are for
flash flooding to occur.
Monitor the latest forecasts and be prepared to take immediate
action if flash flood warnings are issued.

* Surf... along east facing shores... 10 to 15 feet.
* Timing... through 6 PM HST this evening.
* Impacts... very high... expect ocean water surging and sweeping
across beaches... coastal benches... and lava flows creating the
potential for impacts to coastal properties and
infrastructure... including roadways. Powerful longshore and rip
currents will be present at most beaches. Large breaking waves
and strong currents may impact Harbor entrances and channels
causing challenging boat handling.
These dangerous conditions mean that only highly experienced
persons should enter the water. Inexperienced persons should
remain off beaches and adjacent beachfront areas. Large breaking
surf... significant shore break... and dangerous currents make
entering the water very hazardous. Anyone entering the water
could face significant injury or death.
