Subtropical Storm Patty forms west of the Azores

Nov. 2 (UPI) -- Subtropical Storm Patty formed Saturday morning in the Northern Atlantic, the National Hurricane Center said Saturday morning.

Patty was designated as the 16th named storm of the season in the Atlantic in a 5 a.m. ET advisory.

In the 5 p.m. update, Patty had sustained winds of 65 mph and was located about 170 miles west of the Azores. The storm was moving east-southeast at 18 mph in the advisory.

A tropical storm warning is in effect for all of the Azores.

Winds of 40 mph extend outward up to 205 miles from the center.

On the forecast track, Patty is expected to move near or just south of the Azores through Sunday, according to NHC.

"Gradual weakening is expected during the next few days," NHC said. "Patty is forecast to become a post-tropical low late Sundayor Monday."

Swells generated by Patty over the next couple of days are likely to cause life-threatening surf and rip current conditions in the Azores, according to NHC.

Elsewhere in the Atlantic, disorganized showers and thunderstorms over the southwestern Caribbean Sea are associated with a broad area of low pressure. Gradual development of this system is expected with a tropical depression likely to form within the next couple of days. There is a 70% formation chance through 48 hours and 80% for seven days, according to NHC.

Near the Greater Antilles, a large area of disorganized showers and thunderstorms is just north of Puerto Rico and Hispaniola. By early next week, this system is forecast to be absorbed into the low pressure area over the Caribbean Sea, NHC said. The formation chance over 48 hours is 10% and over seven days also 10%, according to NHC.

Of the named storms, 10 were hurricanes, including four major ones: Beryl, Helene, Kirk and Milton.

Beryl, Helen and Milton made landfall in the United States.

The hurricane season runs from June 1 to Nov. 3
