Category 5 hurricanes that have hit the mainland United States of America

1992 Hurricane Andrew
1969 Hurricane Camille
1935 Labor Day hurricane
_
Hurricane Andrew was previously categorized as a Category 4 until 10 years later. With advanced research techniques and technology in the year 2002, they now estimate it was a Category 5.
http://www.nhc.noaa.gov/NOAA_pr_8-21-02.html
http://www.aoml.noaa.gov/hrd/hurdat/andrew_minutes.html
ftp://ftp.nhc.noaa.gov/pub/storm_archives/atlantic/prelimat/atl1992/andrew/

The Hurricane Center's recent research shows more people lose their lives to freshwater floods developing after hurricanes make landfall than from accompanying wind, waves, and storm surge. In fact, nearly half of the 256 fatalities caused by Camille were the result of freshwater flooding.

Another area of huge potential loss, in addition to inland floods and mudslides, is traffic jams during mass evacuations. For example, a highway construction project snarled traffic and left 10,000 people on roadways near Pensacola, Fla., during Hurricane Opal in 1995. If the storm had not taken a turn away from the traffic jam, thousands of people could have been killed.

An overlooked but common cause of deaths is the danger of driving on the road during and just after a hurricane or storm. Falling trees or tree limbs and falling power poles can crush vehicles and its occupants. Electrocutions from downed or flooded power lines are also a hazard.

Hurricane Camille was one of only three Category 5 storms to effect the mainland United States. The first documented was a 1935 hurricane in the Florida Keys.

The destruction caused by hurricanes Charley, Frances, Ivan and Jeanne have prompted the largest relief effort ever [more than 911] undertaken by the Federal Emergency Management Agency. Hurricane Jeanne, the fourth storm to hit Florida in six weeks, makes Florida in 2004 the first state to get pounded by four hurricanes in one season since Texas in 1886.

Larger structures near the coast are damaged by battering waves and floating debris. Low-lying escape routes inland may be cut by rising water 3-5 hours before the hurricane center arrives. Flat terrain 5 feet (1.5 m) or less above sea level flooded inland 8 miles (13 km) or more. Evacuation of low-lying residences within several blocks of shoreline may be required.

The Inland Wind Model

Estimated winds for future reference at Central Marion County, Florida.
Sustained winds = 1 minute average of measured winds. Mobile homes in danger above 70 knots.

Hurricanes crossing over the Ocala area usually came from the Gulf of Mexico or south Florida with average forward speeds of 10 to 15 knots.

Category 5 - 135 kt from the Gulf moving 16 kt = 100 kt

Leading Causes of Tropical Cyclone Deaths in the U.S.(1970-1999)

The greatest inland threat from tropical cyclones is freshwater flooding. Slower storms produce greater amounts of rain and the heaviest rains occur with a storm moving less than 10 mph.

A rule of thumb for estimating the total rainfall in inches is to divide 100 by the forward speed (in mph).

Freshwater Flooding 59%
Freshwater floods accounted for more than half (59%) of U.S. tropical cyclone deaths over the past 30 years. These floods are why 63% of U.S. tropical cyclone deaths during that period occurred in inland counties.

Wind 12%
Surf 12%
Offshore 11%
Tornado 4%
Other 2%
Surge 1%


Hurricane Katrina became the costliest disaster in United States of America's history in 2005. It was only a Category 3 hurricane when it hit the US coastline.

The city government of New Orleans uses M/A-COM ProVoice that radio scanners cannot monitor.

AM broadcast stations that are designated as a local emergency broadcast station should always add shortwave services during times of emergency broadcasting. It is an excellent idea and the New Orleans disaster is a good example but shortwave simulcast started too late after that disaster. Before the next US disaster, broadcasters should plan on doing this because it is another excellent way to get out information. Shortwave simulcast should begin before an impending disaster or immediately afterwards.

Amateur radio operators were listed in the "What Went Right" section of the White House review of the federal response to Hurricane Katrina.

"Other organizations worked tirelessly to assist emergency responders that, due to the storm, did not have the equipment and means to effectively carry out their duties. Amateur Radio Operators from both the Amateur Radio Emergency Service and the American Radio Relay League, monitored distress calls and rerouted emergency requests for assistance throughout the U.S. until messages were received by emergency response personnel. A distress call made from a cell phone on a rooftop in New Orleans to Baton Rouge was relayed, via ham radio, from Louisiana to Oregon, then Utah, and finally back to emergency personnel in Louisiana, who rescued the 15 stranded victims. Ham radio operators voluntarily manned the amateur radio stations at sites such as the National Hurricane Center, Hurricane Watch Net, Waterway Net, Skywarn and the Salvation Army Team Emergency Radio Network."

Remember that you are on your own in any disaster! The ambulance, fire, and police will not come to your aid because they will first protect themselves. Even after a disaster you still may not receive help in time because they will be overloaded helping others and roads may be damaged or blocked by debris. And worst, the authorities will not immediately allow people wanting to help to enter the area until they feel it is safe to do so.

You can lose all communications when trying to contact your loved-ones. No working 911 system, no working cellphones or telephones, no electricity, no Internet. Even satellite phones can get overloaded making them useless. Amateur radio and becomes the only means of communications.

Flood waters, falling tree branches and debris, electrocution from powerlines in water, and violence against people are the most likely causes of death after a storm disaster whether in a vehicle or on foot.
