Pattern
What Jefferson County gets alerted for
Every alert that named Jefferson 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.
Conditions are favourable for flooding. Have a plan in case a warning is issued.
Minor flooding of streets, streams or low-lying areas is expected. Expect ponding on roads and use caution when driving.
Minor coastal flooding is expected, usually around high tide. Expect water on low-lying roads near the shore.
Tropical storm conditions (sustained winds of 39 to 73 mph) are expected within 36 hours. Finish preparations.
Life-threatening inundation from rising water moving inland from the shoreline is expected. Evacuate if ordered.
Conditions are favourable for tornadoes in and near the watch area. Review your shelter plan and stay alert for warnings.
Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.
Tropical storm conditions are possible within 48 hours. Begin preparations.
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.
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.
Life-threatening storm surge is possible. Prepare to evacuate.

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