and where it's headed: Tammy's center is simply east of Guadeloupe as it approaches the northwest. Tammy has actually reinforced decently considering that Friday night.
The storm strengthened into a cyclone on Friday morning in the tropical Atlantic. This is an uncommon location for a typhoon to form this late in the year, according to Dr. Phil Klotzbach, a tropical researcher at Colorado State University.
By early in the week ahead, Tammy should turn northward, then northeastward out to sea and not be an issue for the continental United States.
The path northward away from the Caribbean has ended up being less particular. Tammy was initially anticipated to be recorded by a cold front by the middle of the upcoming week, but computer guidance is now recommending that the storm might drift around between Puerto Rico and Bermuda for some time.
Hurricane Katrina (August 2005) became a big and extremely effective typhoon that caused huge destruction and considerable loss of life. It is the costliest typhoon to ever strike the United States, exceeding the record previously held by Cyclone Andrew from 1992.

The biggest loss of life in Typhoon Katrina was because of flooding caused by engineering defects in the flood defense system, especially the levee around the city of New Orleans. Eventually, 80% of the city, along with large areas in neighboring parishes, were flooded for weeks.
Typhoon cautions have now been issued for a number of islands in the northeast Caribbean. That means hurricane conditions are anticipated in some of these areas. You can see the latest cautions and watches in the map below.
Heavy rainfall, strong winds and high browse from Tammy should spread out across the eastern Caribbean islands through Saturday. Those impacts will last through a minimum of early Sunday in some areas.
Rainfall overalls could be 4 to 8 inches (in your area as much as 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 as much as 4 inches).
T he heavy rainfall could cause flooding and mudslides in some of these areas.
Norma, now a Category 1 storm since 2 p.m. ET, is anticipated to move over or near parts of Mexico's Baja California Sur-- consisting of Cabo San Lucas-- late Saturday afternoon or early evening, the National Cyclone Center stated.
Air Force Reserve Hurricane Hunters observed Norma's center located offshore just west of Cabo San Lucas on Saturday afternoon, and typhoon and conditions were happening over some areas of of southern Baja California Sur, according to the typhoon center.
Norma is anticipated to be somewhat weaker by the time it strikes land, but it still will be a cyclone that could bring life-threatening conditions to a tourist-friendly region that's home to a few hundred thousand people, the cyclone center stated.
In the Atlantic Ocean, meanwhile, Cyclone Tammy-- a Classification 1 storm as of Saturday afternoon-- has set off hurricane warnings for portions of the Leeward Islands, a chain of a number of island countries and territories in between the Caribbean Sea and the open Atlantic. Tammy's winds gained ground to 85 mph.
Neither storm is a threat to the United States.
In the Atlantic, Tammy maintained optimal sustained winds of 85 mph and was focused about 25 miles north-northeast of Guadeloupe, the National Cyclone Center said at 2 p.m. ET.
The Classification 1 hurricane lay about 50 miles southeast of Antigua by Saturday afternoon, the hurricane center said.
Tammy is anticipated to move near or over portions 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 approximately 25 miles from the storm's center and tropical storm-force winds extended outward approximately 125 miles.
Hurricanes in this part of the Atlantic are rare for late October. Tammy is only the 3rd cyclone to form this far southeast in the Atlantic because 1900, according to typhoon specialist Michael Lowry.
It's also the latest-forming typhoon in this part of the Atlantic since 1966, according to Phil Klotzbach, a research study scientist in the Department of Atmospheric Science at Colorado State University.
Typhoon experts previously alerted hurricanes could form in uncommon locations later 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 dangers and could result in flash flooding and mudslides. Rainfall overalls 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 US Virgin Islands, where 1 to 2 inches of rain is more than likely.
Conditions will start to improve from south to north across the island chain by late Sunday as the storm moves north out of the area.
With Tammy in the Atlantic, only two names are left-- Vince and Whitney-- on the standard Atlantic storm name list before the cyclone center turns to an alternate list of names.
