As the Government of Guam, working with partner agencies, continues recovery efforts following Typhoon Sinlaku, coordinated assessments are underway to determine the full extent of the storm’s impact on island infrastructure.

Damage Assessment Training Conducted 

The Guam Fire Department (GFD) advises the community that temporary fire permit exemptions will expire on April 30, 2026.

Effective Friday, May 1, 2026, the following standard fire regulations will be reinstated:

• Fuel Storage: A GFD permit is required for the storage of more than 10 gallons of gasoline or 60 gallons of diesel. The temporary 20-gallon waiver will no longer be in effect.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD), U.S. Naval Base Guam (NBG), and Andersen Air Force Base (AAFB) will conduct routine testing of the vital communication and advance warning system sirens, respectively, on Tuesday, May 5, 2026, starting at 3:15 p.m.

GHS/OCD will test the All Hazards Alert Warning System (AHAWS) sirens in conjunction with NBG and AAFB monthly routine testing of the “Giant Voice (GV)” sirens.

The National Weather Service (NWS) Guam Weather Forecast Office is monitoring the potential for a tropical circulation to form in the next few days somewhere in eastern Micronesia. NWS Guam notes that latest model data suggests this potential circulation could pass near or south of the Marianas in the May 3-6 timeframe.
