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.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Critical fire weather: dry fuels, low humidity and gusty winds. Any fire can spread rapidly; avoid outdoor burning.
Critical fire weather conditions are possible. Postpone outdoor burning.
Flooding of rivers, streams or low-lying areas is occurring or expected. Avoid flooded roads and monitor river levels.
Minor coastal flooding is expected, usually around high tide. Expect water on low-lying roads near the shore.
Heat index values high enough to cause heat illness with prolonged exposure. Drink water, stay in air conditioning and check on neighbours.
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 Port Arthur alerts
How do I get Port Arthur weather alerts on my iPhone?
Install Forecast Bar, add Port Arthur 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, the county Port Arthur 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.
