Caution: The NWS uses sophisticated weather mod-
els to determine an alert’s effective time. However, if
a storm front (for example) moves through an area at
a slower speed than initially predicted, the storm-
related activity might continue after the alert ends.
The end of an alert does not necessarily mean that
the related weather emergency is over.
