and where it's headed: Tammy's center is simply east of Guadeloupe as it approaches the northwest. Tammy has strengthened modestly since Friday night.
The storm strengthened into a typhoon on Friday early morning in the tropical Atlantic. This is an uncommon area for a cyclone to form this late in the year, according to Dr. Phil Klotzbach, a tropical scientist at Colorado State University.
By early in the week ahead, Tammy should turn northward, then northeastward out to sea and not be a concern for the continental United States.
The path northward far from the Caribbean has ended up being less certain. Tammy was at first expected to be recorded by a cold front by the middle of the upcoming week, but computer assistance is now recommending that the storm may drift around between Puerto Rico and Bermuda for a long time.
Typhoon Katrina (August 2005) ended up being a big and incredibly powerful hurricane that triggered enormous damage and substantial death. It is the costliest typhoon to ever strike the United States, exceeding the record previously held by Typhoon Andrew from 1992.
Cyclone Katrina - Wikipedia
The largest death in Cyclone Katrina was because of flooding brought on by engineering defects in the flood protection system, especially the levee around the city of New Orleans. Eventually, 80% of the city, in addition to large locations in surrounding parishes, were flooded for weeks.
Cyclone warnings have actually now been provided for a number of islands in the northeast Caribbean. That suggests cyclone conditions are expected in a few of these areas. You can see the latest warnings and watches in the map below.
Heavy rainfall, strong winds and high surf from Tammy should spread out throughout the eastern Caribbean islands through Saturday. Those effects will last through a minimum of early Sunday in some locations.
Rain overalls could be 4 to 8 inches (locally approximately 12 inches) in the Leeward Islands. The northern Windward Islands may see 2 to 4 inches of rain (locally as much as 6 inches). Parts of eastern Puerto Rico and the Virgin Islands could see 1 to 2 inches of rainfall (in your area up to 4 inches).
T he heavy rainfall could trigger flooding and mudslides in a few of these locations.
Norma, now a Classification 1 storm as of 2 p.m. ET, is anticipated to move over or near parts of Mexico's Baja California Sur-- including Cabo San Lucas-- late Saturday afternoon or early evening, the National Typhoon Center stated.
Air Force Reserve Typhoon Hunters observed Norma's center located offshore just west of Cabo San Lucas on Saturday afternoon, and hurricane and conditions were occurring over some locations of of southern Baja California Sur, according to the typhoon center.
Norma is anticipated to be slightly weaker by the time it strikes land, but it still will be a typhoon that might bring life-threatening conditions to a tourist-friendly region that's home to a few hundred thousand people, the cyclone center said.
In the Atlantic Ocean, on the other hand, Cyclone Tammy-- a Classification 1 storm since Saturday afternoon-- has actually set off hurricane warnings for parts of the Leeward Islands, a chain of a number of island nations and territories in between the Caribbean Sea and the open Atlantic. Tammy's winds picked up speed to 85 mph.
Neither storm is a threat to the US.
In the Atlantic, Tammy kept optimal sustained winds of 85 miles per hour and was centered about 25 miles north-northeast of Guadeloupe, the National Typhoon Center stated at 2 p.m. ET.
The Classification 1 typhoon lay about 50 miles southeast of Antigua by Saturday afternoon, the typhoon center stated.
Tammy is anticipated to move near or over parts of the Leeward Islands-- including Guadeloupe and Antigua and Barbuda-- through Saturday night, and after that move north of the northern Leeward Islands on Sunday.
Hurricane-force winds extended outside up to 25 miles from the storm's center and tropical storm-force winds extended external up to 125 miles.
Hurricanes in this part of the Atlantic are uncommon for late October. Tammy is just the 3rd hurricane to form this far southeast in the Atlantic since 1900, according to hurricane professional Michael Lowry.
It's also the latest-forming cyclone in this part of the Atlantic considering that 1966, according to Phil Klotzbach, a research researcher in the Department of Atmospheric Science at Colorado State University.
Cyclone experts previously alerted cyclones might form in uncommon locations later on in the season this year because of the incredibly warm Atlantic Ocean.
A storm rise of 1 to 3 feet is possible for parts of the Leeward Islands.
Heavy rainfall will be among the storm's most severe hazards and might lead to flash flooding and mudslides. Rain totals for the Leeward Islands are anticipated to be 4 to 8 inches, but could reach a foot in places where the heaviest rain sets up. Rain should be lighter in Puerto Rico and the British and United States Virgin Islands, where 1 to 2 inches of rain is more than likely.
Conditions will begin to improve from south to north across the island chain by late Sunday as the storm moves north out of the region.
With Tammy in the Atlantic, just 2 names are left-- Vince and Whitney-- on the basic Atlantic storm name list before the hurricane center turns to an alternate list of names.
