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 strengthened into a typhoon on Friday early morning in the tropical Atlantic. This is an unusual area 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 a concern for the continental United States.
The path northward far from the Caribbean has actually become less particular. Tammy was at first anticipated to be caught by a cold front by the middle of the upcoming week, however computer system guidance is now suggesting that the storm might wander around between Puerto Rico and Bermuda for a long time.
Hurricane Katrina (August 2005) ended up being a large and extremely effective hurricane that triggered enormous destruction and substantial death. It is the costliest hurricane to ever hit the United States, exceeding the record previously held by Hurricane Andrew from 1992.

The largest death in Hurricane Katrina was due to flooding triggered by engineering defects in the flood defense system, particularly the levee around the city of New Orleans. Ultimately, 80% of the city, in addition to big locations in surrounding parishes, were flooded for weeks.
Cyclone warnings have actually now been provided for several islands in the northeast Caribbean. That implies hurricane conditions are anticipated in a few of these areas. You can see the current cautions and watches in the map below.
Heavy rainfall, strong winds and high browse from Tammy need to spread out throughout the eastern Caribbean islands through Saturday. Those effects will last through at least early Sunday in some locations.
Rain overalls could be 4 to 8 inches (in your area approximately 12 inches) in the Leeward Islands. The northern Windward Islands might see 2 to 4 inches of rain (in your area up to 6 inches). Parts of eastern Puerto Rico and the Virgin Islands could see 1 to 2 inches of rains (in your area up to 4 inches).
T he heavy rainfall could cause flooding and mudslides in some of these areas.
Norma, now a Classification 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 Cyclone 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 occurring over some areas of of southern Baja California Sur, according to the cyclone center.
Norma is anticipated to be somewhat weaker by the time it hits land, however it still will be a hurricane that might bring dangerous conditions to a tourist-friendly area that's home to a few hundred thousand people, the hurricane center said.
In the Atlantic Ocean, on the other hand, Cyclone Tammy-- a Classification 1 storm since Saturday afternoon-- has actually triggered typhoon cautions for parts of the Leeward Islands, a chain of several island countries and areas 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 preserved maximum 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 cyclone was located about 50 miles southeast of Antigua by Saturday afternoon, the cyclone 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 external as much as 25 miles from the storm's center and tropical storm-force winds extended outside as much as 125 miles.
Hurricanes in this part of the Atlantic are uncommon for late October. Tammy is just the 3rd cyclone to form this far southeast in the Atlantic since 1900, according to cyclone specialist Michael Lowry.
It's likewise the latest-forming cyclone in this part of the Atlantic since 1966, according to Phil Klotzbach, a research study researcher in the Department of Atmospheric Science at Colorado State University.
Cyclone professionals formerly cautioned cyclones could form in unusual areas later on 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 serious hazards and might result in flash flooding and mudslides. Rainfall totals for the Leeward Islands are anticipated to be 4 to 8 inches, but could reach a foot in places where the heaviest rain establishes. Rain must 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 enhance 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, just two names are left-- Vince and Whitney-- on the standard Atlantic storm name list before the hurricane center turns to an alternate list of names.
