- What makes an active hurricane season?
- What are the primary weather hazards we need to
be prepared for?
4So what makes an active season?
5Critical component Sea Temps!
6Warm sea temps greater potential
7HURRICANE PREPAREDNESS
- Before a storm threatens
- When a storm threatens
- Weather information sources
- Clues to an increasing threat
- Concluding thoughts
8HURRICANE PREPAREDNESSBEFORE A HURRICANE
THREATENS

protect windows - Know electrical, water, gas shut off valves
- Review working condition of emergency equipment
including flashlights and battery powered
radios - Have cache of non-perishable food and water
11COASTAL HOME PREPAREDNESS
Board up windows if sustained wind speeds may
reach 60 mph or greater

hurricanes accelerate and may arrive hours sooner
than forecasted
17Boat may not be only item you need to move!
- When hurricane threatens, remember also to
- Secure potentially dangerous items such as
propane tanks - Collect/store loose objects such as lawn
furniture, trash cans, etc. - Board up windows and doors if exposed to high
winds (5/8 thick plywood)
18OTHER PREPAREDNESS ACTIONS WHEN HURRICANE
THREATENS
- Check supply of batteries
- Never use candles
- Check supply of nonperishable food and water
- Fill-up with gas and money
- Gas pumps and ATMs rely on power

of US radar. - When Public Advisories are issued every 2 hours,
on the hours where no advisory is issued, a
position estimate on the center of the hurricane
is given based on radar. - A Tropical Cyclone Update is issued at any time
in lieu of a special public advisory for changes
in a systems intensity or changes in watches and
warnings.
23National Hurricane Center Products

24Local NWS Tropical Storm/Hurricane Products
- There are several products issued by local NWS
offices when a tropical system approaches, some
of which are part of the routine products they
typically issue. - Hazardous Weather Outlook
- This product should be monitored for any type of
hazardous weather including hurricanes and if a
hurricane has the potential to pose a threat to
an area. It is typically listed in this outlook. - Tropical Storm/Hurricane Local Statements (Issued
every 2-4 hours) - Issued by local NWS Forecast Offices when
Tropical Storm or Hurricane Watches and Warnings
are issued for their area. - These statements give the storm center position,
greater detail on storm surge/tide information,
wind information, inland flood threat, threat for
damaging winds in coastal and inland locations
and any known evacuation notices. - Public Information Statements
- Issued when Tropical Storm/Hurricane Watches and
Warnings are posted with safety and terminology
info for the public.
25Local NWS Tropical Storm/Hurricane Products
- Special/Severe Weather Statements
- These will be issued as required for hurricane
force winds and for when the strongest winds near
the center of a hurricane make landfall. - Flood Watches and Warnings for rivers, streams
and urban areas for excessive rainfall. - Tornado Warnings
- Tornado Warnings are being utilized more
frequently for any potential tornadic signatures
on radar from outer rain bands and for when the
eye of a hurricane makes landfall. - The Storm Prediction Center typically issues a
Tornado Watch along and to the east of the center
of a hurricane, as it in these areas that the
threat for isolated tornadoes can occur within a
hurricane, tropical storm and even remnant
tropical systems.

33SITUATIONAL AWARENESS?
34Do not even think about staying with your boat
