The ingredients for a hurricane include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds aloft. If the right conditions persist long enough, they can combine to produce the violent winds, incredible waves, torrential rains, and floods we associate with this phenomenon.
Each year, an average of eleven tropical storms develop over the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. Many of these remain over the ocean and never impact the U.S. coastline. Six of these storms become hurricanes each year. In an average 3-year period, roughly five hurricanes strike the US coastline, killing approximately 50 to 100 people anywhere from Texas to Maine. Of these, two are typically "major" or "intense" hurricanes (a category 3 or higher storm on the Saffir-Simpson Hurricane Scale).
Can you AIM A HURRICANE? try here
are severe tropical storms that
form in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean. Hurricanes gather heat and energy through contact with warm ocean waters. Evaporation from the seawater increases their power.
Hurricanes rotate in a counter-clockwise direction
around an "eye." Hurricanes have winds at least 74 miles per hour. When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge. Storm surges are very dangerous and a major reason why you MUST stay away from the ocean during a hurricane warning or hurricane.

Surge Vulnerability Facts
(evacuation map of Pinellas County)- From 1990-2008, population density increased by 32% in Gulf coastal counties, 17% in Atlantic coastal counties, and 16% in Hawaii (U.S. Census Bureau 2010)
- Much of the United States' densely populated Atlantic and Gulf Coast coastlines lie less than 10 feet above mean sea level
- Over half of the Nation's economic productivity is located within coastal zones
- 72% of ports, 27% of major roads, and 9% of rail lines within the Gulf Coast region are at or below 4 ft elevation (CCSP, SAP 4-7)
- A storm surge of 23 ft has the ability to inundate 67% of interstates, 57% of arterials, almost half of rail miles, 29 airports, and virtually all ports in the Gulf Coast area (CCSP SAP 4-7)
Discuss the type of hazards that could affect your family. Know your home's vulnerability to storm surge, flooding and wind.

SUPERFISH
MISSION: SUPERFISH
Marine biologist and award-winning filmmaker Rick Rosenthal set out to capture on film the biggest, fastest, most dangerous gamefish in the sea — the ancient creatures known as billfish.
The largest of all billfish is the marlin. They top speeds of 60 miles an hour on migrations that can span 9,000 miles. The largest, always female, weigh in at over 1,000 pounds, and are known as “granders.” Ernest Hemingway immortalized the grander in The Old Man and the Sea, the story of an elderly fisherman locked in a life and death struggle with this apex predator. To Hemingway’s great disappointment, he himself never landed a grander, although his novella captures the impact of this huge and graceful creature.

WHAT IS A BILLFISH?
Just as eagles have done in the sky, billfish have dominated the seas as apex predators for years, and yet we know relatively little about them. Billfish include marlin, sailfish, swordfish and spearfish. Marlin, sailfish and spearfish are members of the family Istiophoridae, and swordfish are members of the family Xiphiidae. Billfish are best known for the elongated nasal bones that form their "bill". Like tunas, their bodies are also built for the endurance and speed needed to travel thousands of miles through the world's oceans in search of food.
Blue Marlin
Makaira nigricans (Atlantic) and M. mazara (Indian and Pacific)
Blue Marlin are found in all of the world's major oceans. They are one of the largest billfish species, and have been known to reach sizes of 1700 pounds (771 kg). Individuals over 350 pounds (159 kg) are most likely female. Atlantic blue marlin undergo rapid growth during the first year or two of their lives; however it typically takes 30 years for one to reach 1,000 pounds (454 kg). Blue marlin have the ability to make incredibly long journeys through the ocean. The record being a trip of 9,254 miles (14,893 km) from Delaware in the U.S. to the island of Mauritius off the southeast coast of Africa in the Indian Ocean.
Black Marlin
Makaira indica
Black marlin are found only in the Indian and Pacific Oceans. Like blue marlin, black marlin are known for making long distance migrations. One individual was recorded to have traveled 9,045 miles (14,556 km) across the Pacific Ocean from Australia to the Pacific coast of Costa Rica.
White Marlin
Tetrapturus albidus
White marlin are found in the Atlantic Ocean and in the Caribbean and Mediterranean Seas. They are among the smallest of the marlin, typically only reaching wei
ghts of 55 pounds (25 kg) and lengths of 5.5 feet (1.5 m). Individuals have been known to reach lengths of 7.5 feet (2.3 m) and weights of 180 pounds (82 kg). This species of marlin is the most frequently caught along the eastern coast of the U.S.
Striped Marlin
Tetrapturus audax
Striped Marlin are found throughout the Pacific and Indian Oceans and occassionaly on the Atlantic side of the Cape of Good Hope. These marlin are known for coming to the surface during strong winds and high waves, where they swim in the direction of the wind.
Sailfish
Istiophorus platypterus (Indo-Pacific) and I. albicans (Atlantic)
Sailfish are best known for their huge, sail-like dorsal fins. This fin can be up to twice the height of the body of the fish. They are the most commonly encountered of all the billfishes. Indo-Pacific sailfish are much larger than their Atlantic counterparts.
Spearfish
Tetrapturus pfluegeri (Atlantic longbill), T. angustirostris (Pacific shortbill) and T. belone (Mediterranean shortbill)
Though spearfish, the smallest of the billfishes, are found in all the world's oceans, they are rarely encountered in much of the world. They have the shortest bills of the billfish. Very little is known about these animals. It is believed that they have the shortest lifespan of the billfish, maturing at 2 years and living no more than 5 years.
Swordfish
Xiphias gladius
Swordfish are found in all of the world's oceans. They are easily identified by their flattened bills, shaped like the blade of a sword. They also differ from other billfish in that they have a single caudal keel, instead of two. They can reach sizes of 1200 pounds (540 kg). Similar to blue marlin, individuals that are over 300 pounds (136 kg) are most likely female. Swordfish have the ability to dive to 2,000 feet (610 m), although large individuals m
ay be seen basking at the ocean's surface during the day.
BF378469 Recapture
TBF hopes you all enjoy seeing where some of our tagged billfish have gone. These maps illustrate a small sample of the recapture data from our conventional
tagging program. TBF is proud to have captains, anglers, and mates eager to tag and report all their billfish catches. TBF could not have the largest private conventional tagging program and best recapture rates for billfish if it wasn't for you.
As a thanks, TBF will now will be releasing periodic posts of our recapture track maps throughout the year on Facebook and on our website (www.billfish.org). If you have any questions please let us know and keep on tagging! We would love to see and hear more of your tagging stories, contact us at tag@billfish.org.
*please note the "push pin" is where the billfish was originally tagged and the "fishing icon" is where billfish was recaptured.
