H ere's where Tammy is located right now . Hurricane Tammy Primary Effects ...
and where it's headed: Tammy's center is simply east of Guadeloupe as it moves toward the northwest. Tammy has actually reinforced decently since Friday night.
The storm enhanced into a cyclone on Friday early 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 must turn northward, then northeastward out to sea and not be an issue for the continental United States.
The route northward away from the Caribbean has become less specific. Tammy was initially expected to be caught by a cold front by the middle of the upcoming week, but computer assistance is now suggesting that the storm might wander around in between Puerto Rico and Bermuda for a long time.
Typhoon Katrina (August 2005) became a big and very effective cyclone that caused huge damage and significant death. It is the costliest hurricane to ever hit the United States, going beyond the record previously held by Typhoon Andrew from 1992.

The biggest death in Typhoon Katrina was due to flooding caused by engineering defects in the flood security system, particularly the levee around the city of New Orleans. Ultimately, 80% of the city, as well as big areas in surrounding parishes, were flooded for weeks.
Hurricane cautions have actually now been issued for a number of islands in the northeast Caribbean. That means typhoon conditions are expected in a few of these locations. You can see the latest cautions and watches in the map below.
Heavy rainfall, strong winds and high surf from Tammy should spread throughout the eastern Caribbean islands through Saturday. Those impacts will last through a minimum of early Sunday in some areas.
Rain overalls could be 4 to 8 inches (locally as much as 12 inches) in the Leeward Islands. The northern Windward Islands might see 2 to 4 inches of rain (locally approximately 6 inches). Parts of eastern Puerto Rico and the Virgin Islands might see 1 to 2 inches of rains (in your area up to 4 inches).
T he heavy rainfall might trigger flooding and mudslides in a few of these areas.
Norma, now a Classification 1 storm as of 2 p.m. ET, is expected 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 Hurricane Center said.
Air Force Reserve Cyclone Hunters observed Norma's center situated offshore just west of Cabo San Lucas on Saturday afternoon, and hurricane and conditions were taking place over some areas of of southern Baja California Sur, according to the hurricane center.
Norma is anticipated to be a little weaker by the time it strikes land, however it still will be a typhoon that might bring dangerous conditions to a tourist-friendly region that's home to a few hundred thousand people, the typhoon center stated.
In the Atlantic Ocean, on the other hand, Hurricane Tammy-- a Category 1 storm since Saturday afternoon-- has actually triggered typhoon cautions 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 miles per hour.
Neither storm is a risk to the United States.
In the Atlantic, Tammy kept maximum sustained 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 typhoon lay about 50 miles southeast of Antigua by Saturday afternoon, the hurricane center stated.
Tammy is expected to move near or over parts of the Leeward Islands-- consisting of Guadeloupe and Antigua and Barbuda-- through Saturday night, and after that move north of the northern Leeward Islands on Sunday.
Hurricane-force winds extended outward up to 25 miles from the storm's center and tropical storm-force winds extended outward as much as 125 miles.
Hurricanes in this part of the Atlantic are uncommon for late October. Tammy is just the third hurricane to form this far southeast in the Atlantic considering that 1900, according to hurricane specialist Michael Lowry.
It's also the latest-forming typhoon 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.
Hurricane professionals formerly cautioned hurricanes could form in unusual areas later on in the season this year because of the remarkably 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 serious risks and might result in flash flooding and mudslides. Rain totals for the Leeward Islands are expected to be 4 to 8 inches, but might reach a foot in places where the heaviest rain establishes. Rain ought to 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 enhance 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 basic Atlantic storm name list before the hurricane center turns to an alternate list of names.
