Tropical Cyclone 12L (Larry) – Last Advisory

IR Satellite Image

time of arrival graphic

LARRY IS NOW A POST-TROPICAL CYCLONE OVER THE LABRADOR SEA…STILL PRODUCING LARGE SWELLS ACROSS ATLANTIC CANADA AND PORTIONS OF THE EAST COAST OF THE U.S

According the NHC Advisory 44…The post-tropical cyclone is moving toward the north-northeast near 48 mph (78 km/h) and this heading with a decrease in forward speed is expected until Larry merges with an extratropical low tonight or early Sunday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Some slight weakening is possible before Larry merges with another extratropical low. Tropical-storm-force winds extend outward up to 310 miles (500 km) from the center.

HAZARDS AFFECTING LAND 

STORM SURGE: Water levels will gradually subside in southeastern Newfoundland today.

SURF: Significant swells from Larry will continue affecting Bermuda, the east coast of the United States, and Atlantic Canada through tonight. These swells are likely to cause life-threatening surf and rip current conditions.

 

Showers and thunderstorms have not become any better organized in association with a tropical wave located just southeast of the Cabo Verde Islands. Environmental conditions appear generally conducive for gradual development, and a tropical depression is likely to form late this weekend or early next week while the system moves westward over the far eastern Atlantic. Regardless of development, this disturbance is likely to bring gusty winds and locally heavy rain across the Cabo Verde Islands later today and tonight.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 5 days…high…70 percent

>>> Another tropical wave is expected to move off the west coast of Africa in a few days. Some development of this system will be possible through the middle of next week while it moves westward across the eastern tropical Atlantic Ocean.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…20 percent

>>> An area of low pressure is expected to form near the southeastern Bahamas in a few days. Gradual development of this system is possible thereafter as it moves northwestward across the western Atlantic.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 5 days…low…20 percent

 

Gulf of Mexico

A tropical wave and an upper-level trough continue to produce a large area of disorganized showers and thunderstorms over portions of southeastern Mexico and the southern and central Gulf of Mexico. Although upper-level winds are not conducive for development currently, they are expected to become more favorable for the system during the next day or so. A tropical depression is likely to form on Sunday or Monday while the disturbance moves northwestward and then northward near the coast of northeastern Mexico. Further development will be possible through the middle of next week if it remains over water, and interests along the western and northwestern Gulf coast should monitor the progress of this system. An Air Force Hurricane Hunter aircraft is scheduled to investigate the system tomorrow.

Regardless of development, this disturbance is expected to produce heavy rain across portions of Central America and the Yucatan Peninsula through today which may lead to flash flooding and mudslides. By late this weekend, heavy rain will likely reach portions of the western Gulf coast, including coastal Texas and Louisiana through the middle of next week. Localized significant rainfall amounts will be possible, potentially resulting in areas of flash and urban flooding.

* Formation chance through 48 hours…high…80 percent
* Formation chance through 5 days…high…90 percent
