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

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,

Gabrielle has strengthened into the second major hurricane of the season as it approached Bermuda early this week. Additional tropical activity in the Atlantic is likely to increase soon, according to AccuWeather meteorologists,

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).

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

While Hurricane Humberto continues to strengthen out in the Atlantic Ocean, it's not the storm that poses the most danger to U.S. shores.

At 8 p.m. Tuesday, the National Hurricane Center issued an advisory stating that Category 4 Hurricane Gabrielle is in the Atlantic Ocean, 445 miles east-northeast of Bermuda and 1,710 miles west of the Azores. Packing maximum sustained winds of 130 mph, the hurricane is tracking to the east-northeast at 20 mph.
