What to do
A Coastal Flood Advisory means that minor tidal flooding is expected. Minor tidal flooding often results in some road closures. Usually, the most vulnerable roadways will flood. Do not leave your vehicle at a location that is prone to tidal flooding. Do not drive your vehicle through flood waters. The water may be deeper than you think it is. You will be putting yourself in danger and your vehicle may be damaged, leading to costly repairs. Visit the National Water Prediction Service at https://water.noaa.gov/wfo/phi for additional water level and flood impact information for your local tide gauge.
Warning, watch or advisory?
- Warning — the hazard is happening or about to. Act now: take shelter, leave, or stay off the roads.
- Watch — conditions could produce it. Have a plan and keep checking.
- Advisory — less serious, but a nuisance or a risk for some people, such as drivers or those sensitive to heat.
- Statement — information that does not reach advisory level.

What this page shows, and what it misses
Alerts come straight from the US National Weather Service (api.weather.gov), refreshed every five minutes. The most serious appear first. Alert text is the NWS's own; times in each headline are the issuing office's local time. Local emergency managers sometimes issue orders — evacuations, boil-water notices — that are not weather alerts and do not appear here. Severe and extreme alerts also go into our United States incident record. Method: about · credits: licences.
