Southeast U.S. may face 'Troptober'

Tropical Storm Georgette brings more wet misery to Mexico
La Paz, Mexico (AFP) Sept 21, 2010 - Flood-battered Mexico suffered Tuesday from yet another deluge, this time from Tropical Storm Georgette which barreled ashore in Baja California bringing up to 15 centimeters (six inches) of rain. The Pacific storm drenched the resort town of Cabo San Lucas at the Baja peninsula's southern tip, lashing the region with sustained winds of 65 kilometers (40 miles) per hour. "We have already evacuated around 1,000 families" from areas vulnerable to flooding and storm surges, said Jose Gajon, director of Civil Defense for Baja California Sur state. Earlier in the day authorities halted all maritime traffic in the area amid forecasts of four-meter (13-foot) swells.

The US National Hurricane Center (NHC) said it forecast Georgette would move out over the Gulf of California late Tuesday and maintain its strength before churning ashore in mainland Mexico sometime Wednesday afternoon or evening. Up to 25 centimeters (10 inches) of rain was possible in isolated areas. "These rainfall amounts may produce life-threatening flash floods and mud slides," the NHC said in a bulletin. Georgette arrived barely four days after powerful Hurricane Karl ravaged much of the country's coast along the Gulf of Mexico, leaving 22 people dead and about 500,000 displaced. Since late August wide swathes of Mexico have been deluged with what authorities have described as the worst rains on record.

The southeastern U.S. faces the possibility of being battered by multiple tropical storms or hurricanes next month in what forecasters have dubbed "Troptober."

The period starting in late September and into October could yield three to five named tropical systems as the waters of the Gulf of Mexico, Caribbean and the southwestern Atlantic are primed to explode, reported Tuesday.

Forecasters are concerned the raging La Nina and its associated cool waters in the tropical Pacific have created a tremendous imbalance, hurricane expert Joe Bastardi said.

Computer models seem to support the concern with a barrage of tropical cyclones predicted to form in succession over the Caribbean and the southwestern Atlantic during the last few days of September through the first part in October.

If the model-based predictions prove accurate, Florida, part of the Gulf Coast, the southern Atlantic seaboard, Cuba, Hispaniola, Puerto Rico and the Bahamas could be in for multiple rounds of heavy rains, gusty winds, rough seas and battering surf, said.

Hurricane Igor lashes eastern Canada, then moves on
Ottawa (AFP) Sept 21, 2010 - Igor was downgraded to a post-tropical storm Tuesday after forcing evacuations of flooded coastal towns in Canada's island Newfoundland province and reportedly sweeping one man out to sea.

Parts of the province were on high alert for most of the day as the hurricane approached from the Atlantic Ocean, unleashing fierce winds and torrential rains.

Public broadcaster CBC said one person was missing after being swept out to sea near Britannia, on Random Island in Trinity Bay. The man fell into a brook leading to the Atlantic Ocean when a roadway crumbled beneath his feet.

Search and rescue efforts were said to be hampered by widespread flooding and washouts of roads.

At 1930 GMT, Igor was about 85 kilometers (53 miles) northeast of Newfoundland's capital Saint Johns, and was moving north at 55 kilometers per hour (34 miles per hour), the Canadian Hurricane Centre said.

"Heavy rainfall should end this evening as Igor moves off to the northeast ... away from Newfoundland," it said.

The storm buffeted eastern Newfoundland, battering the coast with sustained winds of up to 140 kilometers per hours (87 miles per hour) and waves up to six meters (18 feet).

Throughout the day, Igor also dumped more than 200 millimeters (eight inches) of rain on parts of the province.

"Mother Nature is really giving a pounding to the Burin Peninsula (in southern Newfoundland) right now," Royal Canadian Mounted Police Sergeant Boyd Merrill told CBC.

A state of emergency was announced in several coastal towns, forcing their evacuation, while at least one bridge was washed out and many roads were closed, said the provincial transportation ministry.

"Hurricane force winds have been observed by an oil rig, buoy data, ship data, and coastal stations near, and offshore of Southeastern Newfoundland," said the Canadian Hurricane Centre, warning that it could still intensify.

Extra-tropical cyclones occur outside the tropics, and are distinct from hurricanes in that they generate energy from temperature contrasts between warm and cold air masses. Like Igor, they can still carry hurricane-force winds.

Hurricane Igor battered Bermuda on Sunday and Monday with fierce winds and storm surges that flooded its coastlines, flattened palm trees and left most of the island without power.

It is expected to weaken as it moves further north of Newfoundland, reaching Baffin Island and Greenland on Saturday.

Meanwhile the twelfth named storm of the Atlantic season formed earlier Tuesday west of the Cape Verde Islands.

Tropical Storm Lisa was spinning slowly northwestward bearing winds of 75 kilometers (45 miles) per hour, with strengthening expected in the next 48 hours, the NHC said, adding there were no immediate threats to land.
