Latest Update is Here: Hurricane Humberto and Tropical Depression Nine Impact Southeast US and Bahamas, Now This is What You Need to Know

Published on September 29, 2025

By: Tuhin Sarkar

Hurricane Humberto and the developing Tropical Depression nine are set to impact the Southeast U.S. and the Bahamas, bringing heavy rainfall, strong winds, and coastal hazards. AccuWeather® experts say Humberto will pull Tropical Depression 9 out to sea, but the storm’s proximity to the East Coast will still cause significant weather disruptions. With rain, wind, and coastal flooding, the Southeast, including Florida, Georgia, and the Carolinas, should brace for the storm’s effects. As the storm moves north, the Bahamas will also experience worsening conditions.

Humberto Pulls Storm Out to Sea, Impacting the U.S. East Coast

Hurricane Humberto, a powerful storm, is expected to pull Tropical Depression 9 out to sea early this week, minimizing the risk of landfall in the Southeast U.S. Despite this, the East Coast will still face heavy rainfall and coastal flooding. The interaction between these two storms will spare the Southeast from a landfall but will cause dangerous conditions from South Florida to the mid-Atlantic. These areas will experience rough surf, beach erosion, rip currents, and localized flooding. Wind gusts of 40-60 mph are also expected along the coast, with an AccuWeather Local StormMax™ of 80 mph in some regions.

The heavy rains associated with this storm could total up to 8 inches in certain areas. South Carolina and North Carolina could receive between 4-8 inches, with localized flooding being a significant risk. As the storm nears, flash flooding will become a real concern, especially in areas already dealing with drought conditions. This storm also carries the potential for damaging winds, which could knock down trees and lead to power outages, further exacerbating the storm’s impact on residents and travelers alike.

Heavy Rainfall Expected, Coastal Hazards Remain a Concern

The storm’s movement towards the north will bring substantial rainfall to parts of the Southeast U.S., particularly from Florida to North Carolina. While much of the rain will be beneficial for drought-stricken areas, it could trigger dangerous flash flooding in some regions. Areas from Charleston, South Carolina to Wilmington, North Carolina may see rainfall totals of up to 8 inches, with localized flash flooding causing disruption. The heavy downpours could quickly overwhelm drainage systems and lead to hazardous driving conditions.

In addition to rain, coastal regions will experience heightened risks of storm surge, with a 1-3 foot surge possible from the Southeast U.S. to the Carolinas. Coastal erosion and beach inundation will continue to be a significant problem throughout the week. Despite the storm moving away from the coast, the combination of rough surf, strong winds, and the ongoing threat of flash flooding will make coastal regions dangerous. Travelers along the U.S. East Coast are advised to monitor local weather updates and avoid areas with flood risks.

The Bahamas Braces for Impact as Tropical Depression 9 Intensifies

Tropical Depression 9, located near the Bahamas, is forecast to intensify into a tropical storm as it moves northward. As the storm approaches the Southeast U.S. coastline, it will bring heavy rain, gusty winds, and some storm surge to the islands. Although this storm may not directly impact the U.S. East Coast, the Bahamas will bear the brunt of its impacts in the coming days. Early forecasts predict that the depression could become a hurricane off the Southeast U.S. coast by the beginning of the week.

The Bahamas can expect up to 18 inches of rain, particularly across the northern islands, leading to flash flooding risks. Winds of up to 60 mph, with gusts potentially reaching 80 mph, are also expected. The storm will likely bring dangerous conditions to the Bahamas, with storm surges further exacerbating coastal flooding. As the storm intensifies, the islands should be prepared for the potential of more severe conditions, including power outages and property damage.

Hurricane Humberto’s Growing Strength and Threat to Bermuda

Hurricane Humberto, having reached Category 5 strength, continues to grow stronger as it moves through the Atlantic. This storm is the second hurricane of the season to achieve Category 5 status, and it remains a significant threat to the region. While the storm will pass between Bermuda and the U.S. East Coast early this week, it will bring gusty winds and rain to Bermuda, especially from Tuesday to Wednesday.

Bermuda is expected to face tropical conditions once again, with the storm’s proximity causing flooding, wind damage, and coastal hazards. However, the worst impacts will be felt as the storm makes its closest approach, which is forecast for Wednesday night through Thursday. Travelers to Bermuda should prepare for possible travel disruptions, and locals should take precautions against flooding and storm surge.

AccuWeather® RealImpact™ Scale and Storm Warnings

Tropical Depression 9 has been rated a 1 on the AccuWeather RealImpact™ Scale for Hurricanes, indicating localized flooding, damaging winds, and coastal inundation. The storm’s impact on the Bahamas and Southeast U.S. will be felt through flooding, storm surge, and power outages. The RealImpact™ Scale provides a useful way for communities and travelers to gauge the severity of the storm and take appropriate precautions. Localized flooding, downed trees, and beach erosion are expected, but widespread devastation is not anticipated at this stage.

As the storm continues to develop, AccuWeather® urges everyone in the impacted regions to prepare for severe weather. Travelers should avoid areas at risk of flooding, and residents should secure loose outdoor items and prepare for power outages. Despite the storm’s relatively low rating on the RealImpact™ Scale, the combined effects of wind, rain, and coastal hazards are expected to cause significant disruption in vulnerable areas.

Conclusion: Preparing for the Storm’s Impact on the Southeast U.S. and the Bahamas

Hurricane Humberto and Tropical Depression 9 are two storms that will significantly impact the Southeast U.S. and the Bahamas this week. As the storms interact, the threat to the U.S. East Coast diminishes, but coastal hazards, rainfall, and flash flooding remain major concerns. The Bahamas will experience heavy rain and gusty winds as the storm intensifies, while Bermuda will face another round of tropical conditions.

Despite the relatively low classification of Tropical Depression 9 on the AccuWeather RealImpact™ Scale, the storm’s effects will still be felt through localized flooding, power outages, and coastal damage. Travelers in affected areas should stay informed, avoid flooded roads, and prepare for possible disruptions. As these storms move out to sea, the Southeast U.S. and the Bahamas will continue to monitor their progress and prepare for the next wave of impacts.
