A zone is an area where
essentially the same weather is expected, so that
a single forecast can serve as the local forecast
for all communities within the area. Zone
forecasts cover a seven-day period, and have enough
detail to give customers a clear statement of expected
weather. Significant weather events, such
as warnings, watches, and advisories are headlined
in each zone forecast. The zone forecast is
issued around 4am/pm local time, and updated as
needed.
