In the past year the National Weather Service issued 165 alerts for Honolulu County, including 15 flash flood warnings, 12 high surf warnings, 3 high wind warnings and 2 tropical storm warnings.
From the Iowa Environmental Mesonet’s archive of NWS watches, warnings and advisories (VTEC), by the county’s own code and the forecast zones inside it. Each links to the alert's own page, with its text, map, radar and sounding.
The hazard is happening or about to. Act now: a tornado warning means take shelter, a flash flood warning means move to higher ground.
Watch
Conditions favor the hazard. Nothing is happening yet; have a plan and be ready to act if a warning follows.
Advisory
A hazard that is less serious than a warning but can still cause trouble, such as dense fog, heat or light ice.
Statement
Information about weather that does not yet meet a warning: a strong storm, a hydrologic update, or a special weather statement.
Severity (extreme, severe, moderate, minor) is the rating the issuing office gives each product. More on the difference: tornado watch vs. tornado warning. Alerts come from the National Weather Service; follow its instructions and your local officials.
