Global warming: More hurricanes in Hawaii?

sdf

Hurricane Iniki reached Kauai in September 1992 as a Category 4 storm, with winds up to 140 mph.

Study projects two to three times as many storms by the end of the century

By Summit Voice

SUMMIT COUNTY — Large scale shifts in hemispheric circulation patterns and ocean temperatures are likely to steer more hurricanes toward the Hawaiian Islands in coming decades.

A poleward shift of the subtropical jet stream and warmer temperatures over the equatorial central Pacific will combine to make the storms two to three times as likely by the last quarter of the century, according to scientists with the International Pacific Research Center, University of Hawaii at Manoa.

Tropical Storm Norman aims for Mexico

SUMMIT COUNTY — Yet another named eastern Pacific tropical weather system has formed, this time in the channel between Baja, California and the Mexican mainland.

Tropical Storm Norman is generating winds of about 50 mph and is forecast to make landfall somewhere south of Mazatlán within the next 24 hours, then quickly dissipate as it moves inland.

A tropical storm warning has been issued for the west coast of Mexico from La Cruz northward to Huatabampo, where rainfall amounts are expected to range between 4 and 8 inches, with up to 12 inches possible in a few spots.

The rain could produce life-threatening floods in Sinaloa and far western Durango, according to the National Hurricane Center.

SUMMIT COUNTY — One of the strongest hurricanes of the year has formed in the eastern Pacific and could affect the weather in the southwestern U.S. late in the week, according to the National Hurricane Center.

Hurricane Miriam, southwest of the Baja Peninsula, is generating sustained winds of 120 mph and could strengthen a bit more in the next couple of days before weakening as it encounters strong winds from the west.

The storm is forecast to track northward, and even northeastward, which would put the system on track for a landfall along the Baja coast next weekend or early next week, potentially with tropical storm force winds.

Miriam’s outflow is already streaming over the southern tip of Baja. No coastal watches or warning have  been issued for the storm, but the system will likely soon pump up the surf along the Baja Coast.

SUMMIT COUNTY — Carlotta, the season’s third tropical storm of the season has formed over the far southeastern Pacific and is strengthening rapidly, with sustained winds of 50 mph, according to the National Hurricane Center.

Tropical Storm Carlotta is forecast to reach hurricane strength and become a threat to the southern coast of Mexico by Friday. A hurricane watch is already in effect for the Mexican coast between Barra de Tonala and Punta Maldonado, and hurricane warmings are likely in the region soon.

It’s not exactly clear how far north the storm will move before heading back out to sea due to a ridge of high pressure building to the north. The NHC says the storm could stall in the general vicinity of Acapulco during the weekend.

SUMMIT COUNTY — Tropical Storm Bud, swirling over the warm waters of the southeastern Pacific, is forecast to reach hurricane strength by Thursday and could pose a threat to parts of the Mexico coast sometime this weekend.

Forecasters with the National Hurricane Center said it’s the earliest date ever for formation of a second tropical storm in the eastern Pacific basin, beating the previous earliest date by about a week. (more…)
