Pattern
What Tinian Municipality gets alerted for
Every alert that named Tinian Municipality in the last 12 months, by type. Records begin August 30, 2026, so this fills in over the year.
Plain English
What these alerts mean
A warning means the hazard is happening or about to; a watch means conditions favour it; an advisory is a lesser hazard still worth planning around.
Large breaking waves are expected on beaches, with dangerous rip currents. Stay off jetties and out of the water.
Rip currents that can pull swimmers offshore are expected. Swim near a lifeguard and know how to escape a rip.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Tropical storm conditions (sustained winds of 39 to 73 mph) are expected within 36 hours. Finish preparations.
Very large, destructive breaking waves are expected. Stay away from the surf zone entirely.
Significant coastal flooding is occurring or imminent, typically at high tide. Move away from low-lying shoreline areas.
Conditions are favourable for flooding. Have a plan in case a warning is issued.
Significant coastal flooding is possible. Prepare to protect property near the shore.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
Flooding may develop over the coming days as rain, snowmelt or river levels rise.
Tropical storm conditions are possible within 48 hours. Begin preparations.
Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.
A heads-up about conditions that do not meet warning or advisory criteria but still deserve attention, such as a strong storm, patchy fog or a brief burst of snow.

Questions
About Tinian Municipality alerts
How do I get Tinian Municipality weather alerts on my iPhone?
Install Forecast Bar, add Tinian Municipality as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Tinian Municipality then arrives as a push notification at the moment of issue, with Critical Alerts available for the most dangerous warnings. Forecast Bar also runs on iPad, Apple Watch, Mac and Apple TV.
Where do these alerts come from?
From the National Weather Service alert feed (api.weather.gov). NWS issues alerts by county and by forecast zone; this page lists every product that names Tinian Municipality. Forecast Bar checks the feed continuously and this page refreshes within a few minutes of a change.
What is the difference between a watch, a warning and an advisory?
A warning means the hazard is occurring, imminent or very likely: act now. A watch means conditions are favourable for it to develop: prepare and stay informed. An advisory covers a hazard that is less serious than a warning but can still cause real inconvenience or danger if you are not ready for it.
