MIAMI — Hurricane Gabrielle formed Sunday in the open Atlantic southeast of Bermuda, while Tropical Storm Narda emerged well off southern Mexico’s Pacific coast.

Humberto strengthened into a hurricane Friday morning and could reach major hurricane status by the weekend, the National Hurricane Center said.

The Atlantic Basin woke up after an almost three-week slumber. After Gabrielle, we're watching another tropical wave for development. Here's the latest.

Two new tropical systems are on the horizon, with one potentially bringing impacts to the U.S. East Coast as the hurricane season ramps up. Major Hurricane Gabrielle has strengthened into the second major hurricane of the season,

At 5 a.m. Tuesday, the National Hurricane Center issued an advisory stating that Category 4 Hurricane Gabrielle is in the Atlantic Ocean, 305 miles east-northeast of Bermuda and 1,855 miles west of the Azores. Packing maximum sustained winds of 140 mph, the hurricane is tracking northeast at 13 mph.

Hurricane Gabrielle is continuing to barrel across the Central Subtropical Atlantic as a monster Category 4 hurricane on Tuesday morning. In addition to the threat of Hurricane Gabrielle, the National Hurricane Center (NHC) is also monitoring two other areas for potential tropical development in the Atlantic.

Hurricane Gabrielle has gotten its act together as it churns over the open waters of the central subtropical Atlantic, and forecasters say the storm has rapidly intensified into a major hurricane (Category 3 or higher).
