Brewing Tropical Storm Imelda to approach and threaten Carolinas, Georgia
A developing tropical storm (Imelda) will bring heavy rain, strong winds, flooding, and coastal impacts to the Southeast and Carolinas next week, with track and intensity still being closely monitored.
Chief Meteorologist Jon Porter demonstrates how the free AccuWeather app can help you keep track of the storm including any future hurricanes throughout the season. Former Hurricane Erin is used as an example in this video.
Tropical trouble is brewing for the southeastern United States during the first part of the new week in the form of heavy rain, strong winds, flooding and erosive surf. A batch of showers and thunderstorms near the Bahamas has organized into a tropical depression and is forecast to strengthen into the next tropical storm and hurricane of the 2025 Atlantic season.
A tropical wave that AccuWeather's team of hurricane experts has been tracking for two weeks and identified as a tropical rainstorm earlier this week to raise public awareness and assist with preparation is on the cusp of becoming a tropical storm. The depression has begun to spin several hundred miles to the west of powerful Hurricane Humberto over the southwestern Atlantic.

On Saturday, the National Hurricane Center officially classified the rainstorm as Tropical Depression Nine. A tropical storm watch is in effect for the east coast of Florida. A tropical storm warning is in effect for the central and northwestern Bahamas. Maximum sustained winds near the center of the depression were 35 mph.
The next name on the list of tropical storms for this year is Imelda.
The dashed red line represents AccuWeather meteorologists’ forecast path for the eye of the storm. The gray shaded areas on either side of the forecast path represent alternative paths the storm could take based on changing steering conditions. Tropical storm and hurricane conditions will extend well beyond the track of the eye.
Development factors in the coming days for (Imelda) include warm water, a moist atmosphere environment and lowering combative winds (wind shear).
Steering currents for Imelda will be determined by a large area of high pressure over the central Atlantic, the strong circulation of Category 4 Hurricane Humberto tracking near Bermuda, and an area of high pressure in the northeastern United States that may block Imelda's path during the first week of October.
Imelda is forecast to take a slightly west of north track through Tuesday, which will bring the tropical cyclone close to the coasts of Georgia and South Carolina. As Imelda moves along, it is forecast to quickly gain wind intensity and become a hurricane.
Impacts in the Bahamas, Florida
Strong wind gusts, flooding downpours, coastal flooding and dangerous seas will spread northward through the Bahamas. The AccuWeather RealImpact™ Scale for Hurricanes in the Caribbean, the Bahamas and the U.S. is one.
With the center of the storm forecast to remain east of Florida, the worst conditions will stay to the east of the state.
However, seas, breakers and rip currents will increase along the east coast of Florida with some beach erosion. Some bands of heavy rain and gusty thunderstorms may circulate into the Florida Peninsula, especially the eastern and central counties.
Any westward shift in the track or rapid intensification could bring more significant wind, rain and surf conditions to the Peninsula.
Imelda's track scenarios: Multiple possible paths midweek
Imelda will get close enough to the Georgia, South Carolina and North Carolina coasts to bring heavy rain, strong wind gusts, dangerous and erosive surf, and flooding from heavy rain and storm surge effects.
Flooding is often one of the most damaging and dangerous aspects of hurricanes.
At this time, there is a zone where 4-8 inches of rain is forecast to fall on parts of the Carolinas with an AccuWeather Local StormMax™ of 18 inches. Depending on how far inland this level of rainfall occurs, there is a high potential for moderate river flooding.
The heaviest rain and greatest flood potential are forecast to stay well east of the hardest-hit areas of western North Carolina from a year ago, associated with Hurricane Helene. But any westward shift in storm track could bring torrential rain into these areas. Recall that Helene moved inland from the northeast Gulf coast and traveled northward through Georgia to the southern parts of the Appalachians.
The amount of rain could be less overall in the southeastern U.S. if Imelda stops, stalls and shifts away from the Carolina coast at midweek. It is also possible that Imelda could stall offshore and linger for days. The longer Imelda lingers just offshore, the greater the chance of the storm venturing toward the U.S. coast.
The freshwater flooding rainfall will be complicated by storm surge flooding in the barrier islands and the coastal communities on the mainland. Cities such as Charleston and Myrtle Beach, South Carolina, and Wilmington, North Carolina, could face significant flooding.
The river flooding may follow several days after the storm's winds ease. Residents along flood-prone rivers in the Carolina and Georgia midlands and low country should monitor forecasts closely for the potential of inundation this week.
How strong winds and wave action are along the coast, as well as the northern extent of the rain, will depend on Imelda's intensity, track and forward speed.
A hurricane that stalls offshore could result in multiple days of damaging winds and significant coastal erosion. There is the potential for erosive waves to last for a week or more, factoring in Imelda and the more distant and stronger Hurricane Humberto.
There is the possibility that Imelda will only be within 150 miles or so of the coast or turn out to sea—something AccuWeather meteorologists will continue to monitor closely. Such a track would still bring some heavy rain and gusty winds to southeastern Georgia and the central and eastern Carolinas, due to interaction with a non-tropical storm system and the circulation around high pressure in the Northeast that would pump in some Atlantic moisture. However, in this case, most river flooding problems and high levels of damaging winds would be avoided.
Mid-Atlantic impacts from the storm may be limited, but not entirely ruled out
A storm that stalls near the Carolina coast, turns out to sea or wanders just inland over the Carolinas is unlikely to spread rain very far to the north in the mid-Atlantic. At this point, rain heavy enough to cause flooding may reach southeastern and south-central Virginia, with lesser rain extending into central Virginia and the lower part of the Delmarva Peninsula.
The difference in pressure between Imelda and the same high in the Northeast bringing dry air will create stiff northeast breezes in the mid-Atlantic, raising seas and surf to the point where rip currents will be strong and beach erosion and coastal flooding can occur at times of high tide for much of the new week.
The full moon is not until Oct. 6, but astronomical tides tend to increase a couple of days beforehand.
There is little indication at this time that Imelda would track farther north along the coast than the Carolinas and that rain would reach much beyond southern Virginia. However, changes in atmospheric conditions to the north and west of Imelda may change and could lead to rain extending farther north later this week.
