DATASTREME SUPPLEMENTAL SUMMARY
This Supplemental Information File complements the Daily Summary
for
Friday, 26 April 1996
PUBLIC WATCHES and WARNINGS FOR WINDS
The strong winds that have buffeted the Northwest to the Northern
Plains has necessitated the National Weather Service to issue
statements to the public that pertain to winds that may not necessarily
be associated with local convective storms (i.e., thunderstorms)
nor tropical systems (e.g., hurricanes). One segment of the public
targeted are those who drive "high profile vehicles",
such as tractor trailers or campers, that can be tipped over by
the winds.
- A "high wind warning" is issued to warn the
public that sustained winds of 40 mph or greater are expected
to last for 1 hour or longer. This warning is also used if winds
of 58 mph or greater are anticipated for any time duration.
- A "wind advisory" is issued to acquaint the
public of anticipated sustained wind speeds of 30 mph or greater
lasting one hour or longer, or gusts to 45 mph for any duration.
