Pattern
What Onslow County gets alerted for
Every alert that named Onslow County 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.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
A storm with hail of 1 inch or larger, winds of 58 mph or more, or both, is occurring or imminent. Move indoors and away from windows.
Conditions are favourable for severe thunderstorms with large hail or damaging wind. Keep an eye on the sky and on warnings.
Heat index values high enough to cause heat illness with prolonged exposure. Drink water, stay in air conditioning and check on neighbours.

Questions
About Jacksonville alerts
How do I get Jacksonville weather alerts on my iPhone?
Install Forecast Bar, add Jacksonville as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Onslow County 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 Onslow County, the county Jacksonville sits in. 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.
