Storms and Floods

Tropical Storms

In the Atlantic Ocean:

Tropical depression Gabrielle is located approximately about 600 mi. (965 km) SSE of Nantucket, Massachusetts. On the forecast track, the centre of Gabrielle will continue moving away from Bermuda, remain well offshore of the U.S. East Coast, and approach Nova Scotia Friday evening. Some slight strengthening is possible tonight and Friday. Gabrielle is forecast to become a Post-tropical cyclone when it nears Nova Scotia late Friday.

Tropical Storm Gabrielle blew past Bermuda Tuesday night, bringing sustained winds of 40 mph, gusting to 53 mph, along with just over an inch of rain to the Bermuda Airport. Satellite loops show that high wind shear of 20 - 25 knots has ripped apart Gabrielle, leaving the storm with almost no heavy thunderstorms, exposing the low level circulation to view. Wind shear is expected to remain high for the next two days, which will likely keep Gabrielle from strengthening. On Friday and Saturday, moisture from Gabrielle or its remnants will likely bring heavy rain to the Canadian Maritime Provinces.

Hurricane Humberto is located about 395 mi (630 km) NW of the Cape Verde Islands. It appears that Humberto may be at its peak intensity. There are suggestions by the global models that Humberto may attempt a comeback starting around day 5, but it is quite uncertain how much of a tropical cyclone will be remaining at that time after experiencing substantial vertical shear for nearly four days.

In the Pacific:

Today at 12:15 a.m., Guam time, the Joint Typhoon Warning Centre issued a tropical cyclone formation alert on a disturbance about 470 miles north-northeast of Guam. Initial track has it headed west-northwest.

NewsBytes:

Heavy floods triggered a landslide in Askitol, a village in Zibak district in Afghanistan. Four people lost their lives while twenty others are still missing. The floods also washed away 34 houses and 140 head of cattle.
