FLASH FLOOD WATCH THROUGH SATURDAY MORNING

…FLASH FLOOD WATCH IN EFFECT FROM THURSDAY AFTERNOON THROUGH
SATURDAY MORNING FOR THE BIG ISLAND…

.Deep tropical moisture will move up into the Big Island on
Thursday as Tropical Cyclone Erick passes just south of the island.
Easterly winds will push this moisture up the windward slopes of
the Big Island producing periods of heavy rainfall. The highest
threat for flash flooding will occur along the southeast and east
facing slopes of the island.

* Moisture from Tropical Cyclone Erick is expected to move over
the Big Island starting Thursday afternoon. Intense rainfall and
Flash Flooding are possible as the cyclone passes south of the
state, especially along the east and southeast facing slopes.

* Flood prone areas, such as low spots in roads, may become
impassable due to fast flowing water or deep ponding. The main
flooding impacts are expected to occur from Hilo to Naalehu,
with lower flooding potential elsewhere on the Big Island.
Instructions: A Flash Flood Watch means that conditions are favorable for flash flooding. Flash flooding is LIFE THREATENING. Do not cross fast flowing water in your vehicle or on foot. Monitor later forecasts and be prepared to take action if a Flash Flood Warning is issued. If you experience heavy rain or rising water, head to higher ground immediately.
