and where it's headed: Tammy's center is simply east of Guadeloupe as it approaches the northwest. Tammy has strengthened modestly because Friday night.
The storm reinforced into a hurricane on Friday early morning in the tropical Atlantic. This is an uncommon place 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 an issue for the continental United States.
The path northward away from the Caribbean has actually ended up being less specific. Tammy was initially expected to be recorded by a cold front by the middle of the upcoming week, but computer system assistance is now suggesting that the storm may drift around in between Puerto Rico and Bermuda for some time.
Typhoon Katrina (August 2005) became a big and exceptionally effective hurricane that caused massive destruction and considerable loss of life. It is the costliest typhoon to ever hit the United States, going beyond the record previously held by Hurricane Andrew from 1992.
Typhoon Katrina - Wikipedia
The biggest death in Cyclone Katrina was because of flooding triggered by engineering defects in the flood security system, especially the levee around the city of New Orleans. Ultimately, 80% of the city, in addition to large locations in surrounding parishes, were flooded for weeks.
Typhoon warnings have actually now been released for a number of islands in the northeast Caribbean. That means typhoon conditions are anticipated in a few of these areas. You can see the latest cautions and watches in the map listed below.
Heavy rainfall, strong winds and high surf from Tammy must spread across the eastern Caribbean islands through Saturday. Those effects will last through a minimum of early Sunday in some locations.
Rain totals 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 (in your area up to 6 inches). Parts of eastern Puerto Rico and the Virgin Islands could see 1 to 2 inches of rainfall (in your area as much as 4 inches).
T he heavy rainfall could cause flooding and mudslides in some of these areas.
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-- consisting of Cabo San Lucas-- late Saturday afternoon or early evening, the National Cyclone Center said.
Flying Force Reserve Typhoon Hunters observed Norma's center situated offshore simply west of Cabo San Lucas on Saturday afternoon, and cyclone and conditions were occurring 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 hurricane that could bring lethal conditions to a tourist-friendly area that's home to a couple of hundred thousand people, the typhoon center stated.
In the Atlantic Ocean, on the other hand, Typhoon Tammy-- a Classification 1 storm as of Saturday afternoon-- has triggered cyclone cautions for parts of the Leeward Islands, a chain of numerous island countries 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 US.
In the Atlantic, Tammy preserved optimal sustained winds of 85 mph and was centered about 25 miles north-northeast of Guadeloupe, the National Hurricane 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 said.
Tammy is expected 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 up to 25 miles from the storm's center and tropical storm-force winds extended external as much as 125 miles.
Hurricanes in this part of the Atlantic are rare for late October. Tammy is only the third cyclone to form this far southeast in the Atlantic given that 1900, according to typhoon expert Michael Lowry.
It's also the latest-forming cyclone in this part of the Atlantic because 1966, according to Phil Klotzbach, a research researcher in the Department of Atmospheric Science at Colorado State University.
Hurricane experts formerly cautioned cyclones could form in uncommon areas later on 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 serious threats and might result in flash flooding and mudslides. Rainfall totals for the Leeward Islands are anticipated to be 4 to 8 inches, but might reach a foot in places where the heaviest rain sets up. Rain should be lighter in Puerto Rico and the British and United States Virgin Islands, where 1 to 2 inches of rain is most 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, 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.
