What You Should Do Now
- Turn Around, Don’t Drown. Never drive through flooded roadways. Most flood deaths occur in vehicles.
- Move to higher ground if you are in a flood-prone or low-lying area.
- Avoid creeks, streams and drainage areas, which can rise rapidly.
- Secure loose outdoor objects that could be blown around by strong winds.
- Seek safe shelter inside a building or vehicle during lightning.
- Report observed flooding to local emergency services or law enforcement when it is safe to do so.
- Continue monitoring official updates from NWS Guam and GHS/OCD.
