The National Weather Service (NWS), Weather Forecast Office Guam has the following advisories in effect:

An airport wind advisory is in effect for the Guam International Airport Authority until 6 p.m. this evening. East winds at 15 to 20 knots with gusts to 30 knots are expected.

red flag warning is in effect for Guam until 6 p.m. this evening. A red flag warning means that critical fire weather conditions are either occurring now or will shortly. A combination of strong winds, low relative humidity, and warm temperatures will create ideal conditions for rapid spread of wildfires.

fire weather watch will be in effect for Guam from 6 p.m. through Friday afternoon. A fire weather watch means that critical fire weather conditions are forecast to occur. East winds at 15 to 20 mph with gusts of 25 to 30 mph, especially in higher terrain, are expected. Any fires that develop will spread rapidly. Outdoor burning is not recommended.

high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through Sunday afternoon. Rip currents are powerful channels of water flowing quickly away from shore. NWS advised trade-wind swell and wind waves are expected to produce surf up to 9 feet along east facing reefs through tonight increasing to 8 to 10 feet Friday.

Rip currents can sweep even the best swimmers away from shore into deeper water. If caught in a rip current, relax and float. Do not swim against the current. If able, swim parallel to the shore and back toward the beach when possible. If unable to escape, face the shore and call or wave for help. Rip currents are life threatening.

small craft advisory remains in effect for the coastal waters of Guam, Rota, Tinian, and Saipan until 6 p.m. this evening. East winds of 15 to 20 knots with frequent gusts to 25 knots are expected and will produce hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid boating in these conditions.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to avoid hazardous seas, until conditions subside. Heed the advice of any signs including beach closures, beach patrol flags, and the advice of lifeguards or emergency personnel. The community is advised to avoid outdoor burning.
