Tropical Storm Risk (TSR), a London-based group of scientists, said they expected 14 tropical storms for the Atlantic during the season, which runs from June 1 to November 30.

Eight of these will be hurricanes and three will be intense hurricanes, it said.

Four tropical storms will make landfall on the United States, two of them hurricanes, TSR said.

On June 1, University of Colorado climatologists Philip Klotzbach and William Gray forecast 17 tropical storms in the Atlantic, nine of which would become hurricanes. Five of these would be intense hurricanes.

These are rated Category Three or higher on the five-point Saffir-Simpson scale. Level three storms on the scale have driving winds of at least 111 miles (178 kilometers) per hour, capable of knocking down large trees and destroying mobile homes.

TSR (www.tropicalstormrisk.com) groups scientists from University College London's Benfield Hazard Research Centre, which is sponsored by the reinsurance industry. TSR has been in operation for four years and has a strong record for accuracy.

In a press release, TSR said the data for its 2006 forecast is based on the sea surface temperature and trade wind speed in the Caribbean and tropical North Atlantic, which are the two main drivers for whipping up hurricanes.

Lead scientist Mark Saunders said 2003-2005 saw the highest three-year total number of US hurricane landfalls -- 11 -- since 1900 and the highest three-year total number of North Atlantic hurricanes (31) since reliable records began.

Based on current and projected climate signals, there is a 74-percent likelihood that 2006 will be in the top one-third of years for highest storm activity, said Saunders.

"Despite this forecast, the chance of 2006 seeing hurricane activity as high as in 2005, which was the most active and destructive season on record, is low," he added.

"The current forecast is 20 percent lower than at this time last year. In particular, we expect the Gulf of Mexico to witness far fewer intense hurricanes than in 2005."

The biggest storm of last year's season was Hurricane Katrina, a category-three event which killed 1,300 people in the southern United States and left around 100,000 displaced.

In all, 2005 saw a record 15 hurricanes among an unprecedented 28 named storms that formed in the Atlantic. For the first time on record, seven of the hurricanes were considered major, meaning they hit category three or higher.

It was also the costliest hurricane season, with damage estimated at more than 100 billion dollars.
