and where it's headed: Tammy's center is simply east of Guadeloupe as it approaches the northwest. Tammy has enhanced modestly given that Friday night.
The storm enhanced into a typhoon on Friday early morning in the tropical Atlantic. This is an unusual place for a hurricane 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 must turn northward, then northeastward out to sea and not be an issue for the continental United States.
The route northward far from the Caribbean has become less certain. Tammy was initially expected to be recorded by a cold front by the middle of the upcoming week, but computer system guidance is now suggesting that the storm might drift around in between Puerto Rico and Bermuda for a long time.
Cyclone Katrina (August 2005) ended up being a large and exceptionally effective typhoon that triggered huge destruction and considerable loss of life. It is the costliest cyclone to ever strike the United States, going beyond the record previously held by Typhoon Andrew from 1992.

The biggest death in Cyclone Katrina was due to flooding caused by engineering flaws in the flood defense system, particularly the levee around the city of New Orleans. Eventually, 80% of the city, along with big areas in surrounding parishes, were flooded for weeks.
Typhoon cautions have now been issued for several islands in the northeast Caribbean. That implies typhoon conditions are expected in some of these locations. You can see the current warnings and watches in the map listed below.
Heavy rainfall, strong winds and high surf from Tammy ought to spread out across the eastern Caribbean islands through Saturday. Those impacts will last through at least early Sunday in some locations.
Rainfall overalls could be 4 to 8 inches (in your area up to 12 inches) in the Leeward Islands. The northern Windward Islands may see 2 to 4 inches of rain (locally up to 6 inches). Parts of eastern Puerto Rico and the Virgin Islands might see 1 to 2 inches of rainfall (locally approximately 4 inches).
T he heavy rainfall could cause flooding and mudslides in a few of these locations.
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-- including Cabo San Lucas-- late Saturday afternoon or early evening, the National Hurricane Center said.
Air Force Reserve Typhoon Hunters observed Norma's center located offshore just west of Cabo San Lucas on Saturday afternoon, and cyclone and conditions were happening over some locations of of southern Baja California Sur, according to the typhoon center.
Norma is expected to be slightly weaker by the time it strikes land, however it still will be a cyclone that could bring lethal conditions to a tourist-friendly area that's home to a couple of hundred thousand people, the typhoon center stated.
In the Atlantic Ocean, meanwhile, Hurricane Tammy-- a Category 1 storm as of Saturday afternoon-- has set off hurricane cautions for portions of the Leeward Islands, a chain of several island nations and territories between the Caribbean Sea and the open Atlantic. Tammy's winds gained ground to 85 miles per hour.
Neither storm is a danger to the US.
In the Atlantic, Tammy maintained optimal continual winds of 85 miles per hour and was centered about 25 miles north-northeast of Guadeloupe, the National Typhoon Center said at 2 p.m. ET.
The Classification 1 cyclone lay about 50 miles southeast of Antigua by Saturday afternoon, the cyclone 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 then move north of the northern Leeward Islands on Sunday.
Hurricane-force winds extended outward as much as 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 uncommon for late October. Tammy is only the third hurricane to form this far southeast in the Atlantic given that 1900, according to cyclone professional 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 specialists previously alerted typhoons could form in uncommon areas later in the season this year because of the extremely warm Atlantic Ocean.
A storm surge of 1 to 3 feet is possible for parts of the Leeward Islands.
Heavy rainfall will be one of the storm's most severe threats and could lead to flash flooding and mudslides. Rain overalls for the Leeward Islands are anticipated to be 4 to 8 inches, however could reach a foot in places where the heaviest rain sets up. Rain must be lighter in Puerto Rico and the British and United States Virgin Islands, where 1 to 2 inches of rain is probably.
Conditions will start to improve from south to north throughout the island chain by late Sunday as the storm moves north out of the area.
With Tammy in the Atlantic, only 2 names are left-- Vince and Whitney-- on the basic Atlantic storm name list before the cyclone center turns to an alternate list of names.
