H ere's where Tammy lies today . Hurricane Tammy Snipers ...
and where it's headed: Tammy's center is just east of Guadeloupe as it moves toward the northwest. Tammy has strengthened modestly since Friday night.
The storm reinforced into a hurricane on Friday morning in the tropical Atlantic. This is an unusual 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 needs to turn northward, then northeastward out to sea and not be a concern for the continental United States.
The path northward away from the Caribbean has become less certain. Tammy was initially expected to be caught by a cold front by the middle of the upcoming week, but computer system guidance is now recommending that the storm might drift around in between Puerto Rico and Bermuda for some time.
Hurricane Katrina (August 2005) ended up being a large and extremely effective typhoon that caused enormous destruction and substantial death. It is the costliest cyclone to ever hit the United States, surpassing the record previously held by Hurricane Andrew from 1992.

The biggest loss of life in Cyclone Katrina was due to flooding brought on by engineering flaws in the flood security system, particularly the levee around the city of New Orleans. Eventually, 80% of the city, along with large areas in neighboring parishes, were flooded for weeks.
Hurricane cautions have now been issued for several islands in the northeast Caribbean. That indicates hurricane conditions are anticipated in some 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 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 (in your area approximately 6 inches). Parts of eastern Puerto Rico and the Virgin Islands might see 1 to 2 inches of rainfall (locally up to 4 inches).
T he heavy rainfall might trigger flooding and mudslides in a few of these locations.
Norma, now a Category 1 storm since 2 p.m. ET, is expected 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 stated.
Flying Force Reserve Typhoon Hunters observed Norma's center located offshore just west of Cabo San Lucas on Saturday afternoon, and cyclone and conditions were taking place over some locations of of southern Baja California Sur, according to the typhoon center.
Norma is anticipated to be a little weaker by the time it strikes land, but it still will be a hurricane that might bring deadly conditions to a tourist-friendly region that's home to a few hundred thousand people, the hurricane center said.
In the Atlantic Ocean, meanwhile, Hurricane Tammy-- a Classification 1 storm as of Saturday afternoon-- has set off typhoon warnings for parts of the Leeward Islands, a chain of several island nations and areas in between the Caribbean Sea and the open Atlantic. Tammy's winds gained ground to 85 mph.
Neither storm is a risk to the United States.
In the Atlantic, Tammy maintained maximum continual winds of 85 miles per hour and was focused about 25 miles north-northeast of Guadeloupe, the National Typhoon Center said at 2 p.m. ET.
The Category 1 hurricane lay about 50 miles southeast of Antigua by Saturday afternoon, the typhoon center said.
Tammy is expected to move near or over parts of the Leeward Islands-- consisting of 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 outside up to 125 miles.
Hurricanes in this part of the Atlantic are uncommon for late October. Tammy is only the third cyclone to form this far southeast in the Atlantic since 1900, according to typhoon professional Michael Lowry.
It's likewise the latest-forming hurricane 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.
Cyclone professionals previously alerted typhoons could form in unusual locations later in the season this year because of the remarkably warm Atlantic Ocean.
A storm surge of 1 to 3 feet is possible for parts of the Leeward Islands.
Heavy rainfall will be among the storm's most severe risks and might result in flash flooding and mudslides. Rain totals 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 US Virgin Islands, where 1 to 2 inches of rain is more than likely.
Conditions will start to improve from south to north throughout the island chain by late Sunday as the storm moves north out of the region.
With Tammy in the Atlantic, only 2 names are left-- Vince and Whitney-- on the standard Atlantic storm name list before the typhoon center turns to an alternate list of names.
