Tropical Depression Nine is moving very slowly at about 3 mph to the northwest over The Bahamas. As Nine continues slowly drifting over the region, it will bring torrential tropical rainfall to The Bahamas, Cuba and may bring tropical storm-force winds to Florida’s East Coast. Georgia, South Carolina and North Carolina residents will want to monitor this storm as heavy coastal rain is likely and track changes with higher inland impact may still develop.Tropical Storm Warnings in FloridaThe National Hurricane Center meteorologists are issuing tropical advisories on Nine and Hurricane Humberto. You can also find tropical advisories in Spanish here for T.D. Nine. Advisories for the massive Hurricane Humberto can be found here; Hurricane Humberto advisories in Spanish can be found here.From Florida to South Carolina, rainfall up to six inches is possible now through Tuesday. Although track uncertainty remains, heavy rain ahead of future Imelda may develop Monday and continue through early Thursday with 10 to 12 inch totals possible along the southern coast of North Carolina. Periods of scattered showers and storms may bring up to two inch totals for the Eastern Piedmont Triad.Tropical Depression Nine rainbands seen from Puerto Rico Nine is slow to progress, track offshore of Carolinas nowTropical Depression Nine is projected to become Tropical Storm Imelda and eventually a Category 1 hurricane; North Carolina inland impacts are lower on the current track for now, but high impacts to the coastal Carolinas are expected as the storm may linger over the warm Gulf Stream current. Nine is much slower in forward speed and growth than original forecast projections therefore, National Hurricane Center meteorologists believe a faster turn to the east may occur.

Challenges include: What happens with the steering currents aloft How much wind shear may impact Nine?

Areas to Watch in the TropicsOver the next few weeks, the WXII 12 First Warning Weather Team will be focused on three main areas for tropical development:The Gulf: Very warm sea surface temperatures can help fledgling storms explode into monster hurricanes quickly under the right atmospheric conditions.Africa: In late summer, waves of low pressure often move from the Sahara Desert into the eastern Atlantic. They can develop into tropical systems over time. The sub-tropical high-pressure system over the Atlantic will often steer these systems through the tropical Atlantic towards Central America and the United States.Southeast U.S. Coast: Weaker, short-lived storms often form in late summer or fall along the old frontal boundaries. Areas of offshore low pressure can become tropical. These storms can become dangerous quickly because they are so close to the coast.Are you prepared for inland tropical impacts in North Carolina and Virginia?September and October are historically the busiest tropical months for the Carolinas.
