When a storm threatens, what should you do? Hurricane preparedness is merely a matter of planning ahead. Hurricane threats come in many forms, including storm surge, high winds, tornadoes, and flooding.

Before the Hurricane Season Begins

Develop a plan. Know your homes vulnerability to the threats above - surge, wind, and flooding. Check your supplies - water, batteries, food. For information on developing a Hurricane Supply kit, see our page on that topic. Know where you can evacuate to - friends, relatives, a hotel?

Know when to take action - Watch vs Warning

WATCH: Hurricane conditions are possible in the specified area of the WATCH, usually within 36 hours.
WARNING: Hurricane conditions are expected in the specified area of the WARNING, usually within 24 hours. Remember that there is no such thing as a "minor hurricane." Category 1 and 2 hurricanes still can do significant damage.

Prepare before a Watch or Warning is issued and be ready to evacuate when the Watch comes or earlier if so instructed.

An Approaching Storm

As a storm approaches, you should prepare your house and your yard. Some things to consider:

  • Turn down the temperature on your freezer and refrigerator as low as possible. This will buy you more time in the event of a power loss. 24 to 48 hours before will cool the food. Avoid opening them whenever possible. If you are evacuating, probably unnecessary.
  • Before you evacuate, call at least one person out of state to let them know your plans.
  • Ensure that your Hurricane Emergency Kit is fully stocked.
  • Charge electronic devices, for example, computers, cell phones, rechargeable batteries, razors, and the like.
  • Make extra ice, bag it - this will be useful to use and to keep the freezer cold.
  • Do the same with your home air conditioner. It gets very hot and very humid very quickly. If you are evacuating, this is not necessary.
  • If you have a generator, do NOT run it inside or near the house. But make sure you have fuel to run it.
  • Make sure your car has fuel.
  • Pick up yard debris - furniture, tools, decorative items, branches - anything loose that could become a missile. We have placed furniture in the pool upon occasion.
  • Secure boats, trailers, campers, RVs, and the like in the safest place you can find. Tie them down, anchor them, or however you can best secure them. But, take into account that there may be a storm surge.
  • Secure all doors and windows with locks, and shutters if available. Plywood, properly secured, can be effective. Don't forget your garage doors.
  • Move items that may be damaged by water to higher areas of your home if you can not take them with you if evacuating. Move them away from windows in case they are broken.
  • Huge items must even be secured in big storms. An engine block was found 40 or 50 feet up in a pine tree in the Homestead (actually Redlands) area after Andrew. Don't think that something is too big to be moved by the wind.
  • Re-check tie-downs.
  • Bring cars, bikes, scooters and anything like that into your garage if possible.
  • Bring in grills or other cooking items.
  • Bring in hoses, trash cans, hot tub covers, wind-chimes, plants.
  • Caulk and fill bathtubs - extra water comes in handy for toilets and more..
  • It may sound strange, but do your laundry, dishes, and take a shower. Why? Because if you lose power, having as much clean as possible will make a big difference.
  • Check if your pool pump should be on or off.
  • Close and fasten gates so they don't swing.
  • Close chimney flues.
  • Close/latch inside doors and cabinets.

     

    If you have time, help your neighbors. Debris in their yards can easily impact your home and yard.

    During a storm.


  • Stay inside, away from windows
  • Be alert for tornadoes
  • Stay away from flood waters and storm surge. It can be deceptively strong.
  • Be aware of the eye. It may be calm, but winds can and will pick up quickly and could catch you outside.
  • Un-plug electronic devices that are not in use to avoid surge damage. This is less likely that during afternoon thunderstorms because lightening is rare in a hurricane, but it is better to be safe.
  • After a Storm

  • Know power safety - avoid downed lines
  • Know food safety - what is good and for how long.
  • Chain saw safety is critical
  • Generator safety is important too
  • Water treatment - whether water needs to be boiled or not.
  • Listen to local officials
  • Use flashlights instead of candles
  • Inspect your home for damage.
  • Stay off roads as much as possible
  • You may need to super-chlorinate your pool
  • Boat Prep

    1. Move life jackets and first aid kits to house
    2. Remove cushions and lose items (e.g. boat tops) and move to garage
    3. Anchor hatch covers
    4. Move to maximum davit height, fasten cables
    5. Unplug davits/lifts
    6. Turn off outside electricity to davits
    7. For our Boston Whaler: put in main plug on boat (take out other plugs)
    8. Tighten down davit locks
    9. Tie down boat with dock lines

    For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

    The National Hurricane Center is issuing advisories Subtropical
    Storm Ernesto located several hundred miles southeast of Cape Race,
    Newfoundland.

    A tropical wave located about 850 miles east-southeast of the
    Windward Islands is producing a large area of cloudiness and
    thunderstorms. Slow development of this disturbance is possible over
    the next few days while the system moves west-northwestward at 15 to
    20 mph. By early next week, however, upper-level winds are expected
    to become less conducive for any significant development to occur
    when the system will be moving over the eastern Caribbean Sea.
    * Formation chance through 48 hours...low...10 percent.
    * Formation chance through 5 days...low...20 percent.

    Subtropical Storm Ernesto Discussion Number   4
    NWS National Hurricane Center Miami FL       AL052018
    1100 PM AST Wed Aug 15 2018
    
    Although inner-core convection has increased since the previous
    advisory, outer banding features have become more fragmented and
    the overall cloud pattern has become elongated north-to-south.
    There are also no signs of any upper-level anticyclonic outflow,
    an indication that Ernesto is still a subtropical cyclone. The
    initial intensity is being maintained at 35 kt based on a 2328Z
    ASCAT pass that showed peak winds of 32 kt in the southeastern
    quadrant, along with a radius of maximum winds of 70-80 nmi. This
    intensity is consistent with a ST2.5/35 kt classification from TAFB.
    
    The initial motion is now north-northeastward or 025/09 kt. Ernesto
    has rounded the subtropical ridge axis to its south, and the
    cyclone should gradually get caught up in the mid-latitude
    westerlies and turn northeastward during the next 12 hours or so.
    A northeastward motion along with a steadily increasing forward
    speed is expected through Friday. The track guidance is tightly
    packed around the previous advisory track, so the new NHC forecast
    track is essentially just an extension of the previous advisory, and
    lies near the track consensus models HCCA and TVCN.  On the forecast
    track, Ernesto is expected to approach Ireland as an extratropical
    gale area on Saturday.
    
    Ernesto is expected to remain over sea-surface temperatures (SST)
    of 25 deg C or warmer for the next 18-24 hours, along with low
    vertical shear conditions of less than 10 kt. These conditions
    should allow for some slight strengthening during that short time
    window. By 36 hours, Ernesto is forecast to be moving over SSTs of
    20 deg C and colder and into a more stable airmass, resulting in a
    degeneration of the inner-core convection. As a result, Ernesto is
    expected to become a post-tropical cyclone by 36 hours, and become
    an extratropical gale area after merging with a frontal zone near
    Ireland and the United Kingdom in about 3 days.
