and where it's headed: Tammy's center is just east of Guadeloupe as it moves toward the northwest. Tammy has actually strengthened decently because Friday night.
The storm strengthened into a typhoon on Friday early morning in the tropical Atlantic. This is an unusual location for a typhoon 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 should turn northward, then northeastward out to sea and not be an issue for the continental United States.
The path northward far from the Caribbean has actually become less certain. Tammy was initially expected to be captured by a cold front by the middle of the upcoming week, but computer assistance is now suggesting that the storm might wander around between Puerto Rico and Bermuda for some time.
Hurricane Katrina (August 2005) became a large and exceptionally powerful cyclone that caused huge destruction and considerable death. It is the costliest typhoon to ever hit the United States, exceeding the record previously held by Hurricane Andrew from 1992.

The largest death in Hurricane Katrina was because of 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, in addition to large areas in neighboring parishes, were flooded for weeks.
Typhoon warnings have now been provided for a number of islands in the northeast Caribbean. That indicates cyclone conditions are expected in some of these locations. You can see the most recent cautions and watches in the map below.
Heavy rainfall, strong winds and high surf from Tammy must spread across 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 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 could see 1 to 2 inches of rainfall (locally up to 4 inches).
T he heavy rainfall might cause flooding and mudslides in a few of these locations.
Norma, now a Classification 1 storm as of 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 Hurricane Center stated.
Flying Force Reserve Hurricane 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 locations of of southern Baja California Sur, according to the hurricane center.
Norma is expected to be somewhat weaker by the time it hits land, but it still will be a typhoon that might bring life-threatening conditions to a tourist-friendly region that's home to a few hundred thousand people, the hurricane center stated.
In the Atlantic Ocean, on the other hand, Hurricane Tammy-- a Category 1 storm as of Saturday afternoon-- has activated hurricane warnings for portions of the Leeward Islands, a chain of a number of island nations and territories 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 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 cyclone was located about 50 miles southeast of Antigua by Saturday afternoon, the typhoon 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 outside 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 rare for late October. Tammy is just the 3rd typhoon to form this far southeast in the Atlantic given that 1900, according to typhoon professional Michael Lowry.
It's also the latest-forming cyclone in this part of the Atlantic given that 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 areas later in the season this year because of the incredibly 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 risks and might result in flash flooding and mudslides. Rain 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 ought to 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 start to enhance from south to north across the island chain by late Sunday as the storm moves north out of the region.
With Tammy in the Atlantic, just 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.
