and where it's headed: Tammy's center is simply east of Guadeloupe as it approaches the northwest. Tammy has actually strengthened modestly given that Friday night.
The storm strengthened into a hurricane on Friday early morning in the tropical Atlantic. This is an uncommon 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 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 specific. Tammy was initially expected to be caught by a cold front by the middle of the upcoming week, however computer guidance is now suggesting that the storm might wander around between Puerto Rico and Bermuda for a long time.
Typhoon Katrina (August 2005) ended up being a large and very effective typhoon that triggered huge damage and significant death. It is the costliest cyclone to ever strike the United States, surpassing the record previously held by Cyclone Andrew from 1992.

The largest death in Hurricane Katrina was because of 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 large areas in neighboring parishes, were flooded for weeks.
Typhoon warnings have now been issued for numerous islands in the northeast Caribbean. That indicates hurricane conditions are expected in a few of these locations. You can see the most recent cautions and watches in the map below.
Heavy rainfall, strong winds and high browse from Tammy ought to spread out across the eastern Caribbean islands through Saturday. Those effects will last through at least early Sunday in some locations.
Rainfall 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 (locally up to 6 inches). Parts of eastern Puerto Rico and the Virgin Islands might see 1 to 2 inches of rains (locally approximately 4 inches).
T he heavy rainfall might trigger flooding and mudslides in some of these areas.
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-- including Cabo San Lucas-- late Saturday afternoon or early evening, the National Typhoon Center said.
Flying Force Reserve Cyclone Hunters observed Norma's center located offshore just west of Cabo San Lucas on Saturday afternoon, and typhoon and conditions were taking place over some locations of of southern Baja California Sur, according to the typhoon center.
Norma is anticipated to be somewhat weaker by the time it strikes land, but it still will be a cyclone that could bring deadly conditions to a tourist-friendly region that's home to a few hundred thousand individuals, the hurricane center said.
In the Atlantic Ocean, meanwhile, Typhoon Tammy-- a Category 1 storm since Saturday afternoon-- has triggered hurricane warnings for parts of the Leeward Islands, a chain of several island countries and territories between the Caribbean Sea and the open Atlantic. Tammy's winds gained ground to 85 mph.
Neither storm is a danger to the US.
In the Atlantic, Tammy maintained optimal sustained 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 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 after that move north of the northern Leeward Islands on Sunday.
Hurricane-force winds extended outward approximately 25 miles from the storm's center and tropical storm-force winds extended outside approximately 125 miles.
Hurricanes in this part of the Atlantic are uncommon for late October. Tammy is just the 3rd typhoon to form this far southeast in the Atlantic since 1900, according to hurricane expert Michael Lowry.
It's also the latest-forming typhoon in this part of the Atlantic considering that 1966, according to Phil Klotzbach, a research scientist in the Department of Atmospheric Science at Colorado State University.
Hurricane professionals formerly warned hurricanes might form in uncommon locations later in the season this year because of the incredibly warm Atlantic Ocean.
A storm rise 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 result in flash flooding and mudslides. Rain overalls 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 needs to 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 begin to improve 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 standard Atlantic storm name list before the typhoon center turns to an alternate list of names.
