Tropical Storm Sam forms; forecast to be major hurricane by Sunday
Loop News 4 hrs ago
The 18th named storm of the Atlantic hurricane season formed on Thursday, with forecasters already forecasting it to become a hurricane by Friday before quickly strengthening to become a major hurricane by Sunday.
Some forecast models indicate that Tropical Storm Sam could become a Category 4 hurricane as it moves westward toward the Leeward Islands.
However, it is uncertain whether it will pose a threat to parts of the Leeward Islands, or curl northward.
According to some simulations, the storm could make a right-hand turn and curve northward over the open Atlantic before reaching the Lesser Antilles, while a few models show the possibility of Tropical Storm Sam becoming a threat in the northern Caribbean.
The National Hurricane Centre (NHC) in Miami said the newly formed storm, with maximum sustained winds near 50 miles per hour, was located about 1,745 miles east southeast of the northern Leeward Islands and was moving westward at 16 miles per hour.

Tropical Storm Sam forms; system is forecast to become major Atlantic hurricane by Sunday
It marks the second-earliest 18th-named storm on record in the Atlantic

Newly formed Tropical Storm Sam has all the makings of an eventual monster as it rolls through the central tropical Atlantic. Forecast to become a major hurricane (Category 3 or higher), it comes barely a week after the historic peak of Atlantic hurricane season, with roughly half the season left to go.
There are some models that suggest that Sam could cruise well into Category 4 territory, whipping up winds in excess of 130 mph as it swings west toward the Leeward Islands. Most forecast simulations project the storm to make a right-hand turn and curve northward over the open Atlantic before reaching the Lesser Antilles, but it will be an extremely close call. A few models do show the possibility of it becoming a threat in the northern Caribbean.
Meteorologists are also tracking multiple additional systems in the Atlantic, including the remnants of Odette, which have been swirling around the North Atlantic for nearly a week now. There are some signs it could regenerate and acquire tropical or subtropical characteristics.
Another tropical wave soon to emerge off the coast of Africa could gradually develop as well, becoming something to watch in the next week or so.
The season so far has featured 18 named storms, including six hurricanes and three major hurricanes. If three more storms form, the National Hurricane Center’s list of storm names will be exhausted, and it will be forced to use a supplementary list developed by the World Meteorological Organization for any additional storms. “It is noteworthy that this is the 2nd earliest formation of the 18th named storm in the Atlantic basin, moving ahead of the 2005 hurricane season, and only trailing last year,” the National Hurricane Center wrote.
