Hurricane Dennis, a category four monster hurricane packing 230kmh winds, which may yet strengthen to a maximum category 5, is about to strike the Gulf Coast of the mainland United States, most probably close to the Alabama, Florida & Mississippi borders.

Dennis has already killed several people in Haiti and Cuba and over 1 million people in Florida, Alabama and Mississippi have been asked to evacuate out of Dennis's expected path. Tropical storm force winds have already started to batter the Gulf Coast and over the coming 24 hours some parts of the coast are expected to receive up to 300mm (12 inches) of rain. Hurricane force winds extend up to 40 miles from the center though the highest winds are focused around the eye. Near its center the hurricane is likely to bring ashore a 15foot storm surge.

Dennis formed in the Carribean sea north of Venezeula around July 4th. During his path north Cuba in particular was very hard hit by the hurricane. It ran up the Island's south coast before crossing close to the capital Havana and as you can see in the following image nearly the entire island experienced at least tropical storm force winds.

National Hurricane Center forecasters had been uncertain whether the Hurricane would regain its strength after crossing Cuba, but in recent hours there is now no doubt that it has. In the most recent National Hurricane Center discussion alert the forecaster states:

"AFTER DEEPENING AT A RATE THAT BORDERED ON INSANE DURING THE AFTERNOON...DENNIS HAS CONTINUED TO STRENGTHEN AT A MORE NORMAL RATE THIS EVENING.

THE COMBINATION OF TIGHT INNER CORE...GOOD TO EXCELLENT OUTFLOW OVER THE NORTHEASTERN SEMICIRCLE...WARM SEA SURFACE TEMPERATURES...AND COLD CONVECTIVE TOPS SUGGESTS THAT DENNIS HAS NOT YET FINISHED STRENGTHENING."

The hurricane is now packing maximum sustained winds of 145 MPH just 10 MPH short of Category 5 levels. Meanwhile at the time of posting this story the eye has another 10-12 hours over warm water.

Hurricane Dennis is the fourth named storm of 2005. Already this year the Gulf Coast has been battered by tropical storms Arlene and Cindy. 2005 is the first year since records began in 1851 that there has been four named storms by this stage in July.

Hurricane Dennis is also the first category 4t storm to strike the mainland United States this early in the season since 1957.
