The National Weather Service (NWS), Weather Forecast Office Guam issued a thunderstorm warning in effect for the Guam International Airport until 1 p.m. for thunderstorms within 5 miles of the airport.

Additionally, a thunderstorm advisory is in effect for the airport until 1 p.m. for thunderstorms possible or occurring within 20 nautical miles of the airport. Be alert and take precautions as required. If lightning is seen or thunder is heard, get indoors or inside a vehicle.

Through today, isolated showers are expected. Tonight, it is expected to be mostly cloudy with isolated showers and thunderstorms.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) advise the community to practice caution if traveling in rainy conditions.

In addition, the National Weather Service (NWS) Guam Weather Forecast Office also issued an urban and small stream flood advisory for eastern Guam, in effect until 1:30 p.m. A flood advisory means river or stream flows are elevated, or ponding of water in urban or other areas is occurring or is imminent.

Heavy rain due to thunderstorms will cause urban and small stream flooding. Up to one inch of rain has already fallen. Additional rainfall of one to two inches is expected over the area, resulting in minor flooding. Some locations that will experience flooding include Dededo, Tamuning, Yigo, Mangilao, Chalan Pago-Ordot, Barrigada, Yona, Agana Heights, Andersen AFB, Mongmong-Toto-Maite, Sinajana, and Asan.

Residents and visitors are advised to take the following precautionary actions:

· Clear drainage areas and unblock clogged storm drains in your area to minimize the chance of flooding.

· If driving, be alert for low visibilities and slippery roads in heavy rain;

· Slow down where water is ponding on the road;

· Turn Around, Don’t Drown. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away;

· Do not camp, park, or hike along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning;

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to be alert for possible additional advisories and practice caution while traveling in rainy conditions, driving below the speed limit and allowing enough braking distance between vehicles.
