The National Weather Service (NWS) continues to forecast possible torrential rainfall, thunderstorms and high winds from Tropical Storm Flossie.

NWS has placed a tropical storm watch for Hawaii and Maui Counties. Flash flood watch for all islands will begin Monday, July 29.

TS Flossie, which is currently about 775 miles east of Hilo, is moving west at 20 mph with sustained winds of 50 mph. NWS expects TS Flossie to continue weakening in its journey.

NWS forecasts six to 10 inches of rain with higher amounts on windward sides. Eastern islands should expect winds 30 to 40 mph and heavy rainfall on Monday. Western islands should expect winds 25 to 35 mph on Tuesday.

High gusts are expected to occur within 70 miles of the center.

NWS estimates surf of 12-18 feet for the Big Island and Maui County and 10-15 feet elsewhere, favoring east-facing shores.

Residents and visitors should monitor weather updates from NWS and the media, continue preparing for potential extreme weather conditions and minimize non-essential travel during heavy rain.

NWS urges the public to be alert to flash flood watches and warnings. Flooding may occur rapidly and threaten life and property. Ground saturation caused by the heavy showers increases the danger of flash floods, mudslides, and rockslides.

State Civil Defense (SCD) reminds residents and visitors to prepare and monitor:

* Be aware of dangers in areas prone to flooding;

* Bring loose items inside;

* clean gutters and culverts;

* minimize travel time;

* If there is the possibility of flooding, move immediately to higher ground. Do not wait for instructions.

SCD outdoor sirens will not sound unless there is a significant change in TS Flossie.

The public is encouraged to continue to prepare for Hawaii’s ongoing wet weather season, which runs from October to March.

The public should take the following precautions:

* Determine if you live or work in a flood zone at www.floodsmart.gov;

* Listen for Flash Flood Watches and Warnings broadcast on radio and TV and

* Reinforce your home against potential flood damage.
