Prepare to evacuate, if advised to do so by the
Governor or elected officials through radio or television announcements.
Plan to evacuate as early as possible before hurricane gale force
winds and storm surge force road closings. Leaving early may also
help you to avoid massive traffic jams encountered during late evacuation
efforts. Listen to the radio and/or television for evacuation and
sheltering information. Storm advisories are issued as follows:
Tropical Storm Watch
Tropical Storm conditions are possible in
the specified area of the Watch, usually within 36 hours.
Tropical Storm Warning

the specified area of the Warning, usually within 24 hours. Hurricane

TERMS TO KNOW
Tropical Depression: A tropical cyclone
with maximum sustained winds near the surface of less than 39 m.p.h.
Tropical Cyclone:
A low pressure weather system in which the central core is warmer
than the surrounding atmosphere. Storms called hurricanes or typhoons
elsewhere are called tropical cyclones in the Indian Ocean and around
the Coral Sea off northeastern Australia.
Tropical Storm Watch: An announcement
for a specific area that a tropical storm or an unexpected tropical
storm condition poses a possible threat within 36 hours.
Tropical Storm Warning: A warning for
tropical storm conditions, including possible sustained winds of
39 to 73 m.p.h. Tropical Storm: Tropical cyclone with 39 to 73 m.p.h.
winds.
Hurricane Watch: "The first alert when
a hurricane poses a possible, but as yet, uncertain threat to the
coastal area, or when a tropical storm threatens the watch area
and has a 50-50 chance of intensifying into a hurricane." When a
watch is issued, everyone in the area should listen for advisories,
watch the probabilities issued by the Hurricane Center and be prepared
to act quickly if a hurricane warning is issued.
Hurricane Warning: "A warning that,
within 24 hours or less, a specific coastal area will experience:
a) sustained winds of 74 m.p.h. or higher and/or b) dangerously
high water or a combination of dangerously high water and exceptionally
high waves, even though winds may be less than hurricane force."
Hurricane: A tropical cyclone with
winds of 74 m.p.h. or more.
Typhoon:
A
hurricane in the north Pacific west of the International Date Line

Saffir -
Simpson Hurricane Scale |
Hurricanes have been classified into five categories
according to their central pressure, wind speed and storm surge:
a Category One hurricane being the weakest and a Category Five hurricane
being the strongest. By using a disaster potential scale, it is
easier to compare different hurricanes and also communicate the
hazards with an approaching hurricane to the public.

DURING
THE HURRICANE
Do not stay in a mobile home during a hurricane.
Even if a mobile home is anchored, there is no guarantee it will
withstand the strong winds of a hurricane. If you are unable to
evacuate before the hurricane hits, stay inside. Do not be fooled
by the eye of the hurricane and its temporary period of peaceful
weather conditions. The length of time within the eye varies from
several minutes to a couple of hours, depending on the size of the
storm. The larger and more intense the hurricane, the larger the
eye. Stay away from windows and glass doors. You could be struck
by flying debris. Continue to listen to your radio or television
for hurricane updates and emergency information.
