Category 4 Hurricane Humberto to create heavy seas and bring rain, wind to Bermuda
Hurricane Humberto is expected to pass near Bermuda during Tuesday and Wednesday, bringing the risk of strong winds, heavy rainfall. The powerful hurricane will create massive seas over the western Atlantic.
AccuWeather’s Geoff Cornish shares the latest updates with Hurricane Humberto.
Category 4 Hurricane Humberto was located about 550 miles south of Bermuda on Sunday evening and is forecast to track about 150 miles to the west and northwest of Bermuda during Tuesday night and Wednesday with the potential for tropical storm force conditions, according to AccuWeather meteorologists.
Humberto is forecast to take a curved path over the west-central Atlantic. Humberto peaked at Category 5 hurricane intensity on the Saffir-Simpson Hurricane Wind Scale for a time on Saturday, when it was packing 160-mph sustained winds. On Sunday morning, the peak winds had dropped slightly to 155 mph. As of Sunday evening, maximum winds were 145 mph. The Saffir-Simpson Scale ranges from 1 to 5, with five being the most intense. At this strength, winds will generate large swells that will spread outward from the center.
The dashed red line represents AccuWeather meteorologists’ forecast path for the eye of Hurricane Humberto. 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.
The swells from Humberto will reach the north- and northeast-facing beaches of the northern Caribbean islands into the first part of this week and the beaches along the Atlantic Coast of the United States for much of this week.

Humberto recently underwent rapid intensification last week, strengthening from a 65-mph tropical storm late Thursday evening to a 145-mph Category 4 hurricane in 24 hours by late Friday evening.

The benchmark for rapid strengthening is 35 mph in 24 hours or less. Days earlier, Gabrielle gained 55 mph of wind in 25 hours. During mid-August, Erin strengthened from a 75-mph Category 1 hurricane to a 160-mph Category 5 in less than 24 hours. Humberto is the second Category 5 hurricane of the season.
As Humberto moves along, its overall size will likely grow due to changes within the eye and could climb back to Category 5 status.
As of Monday morning, hurricane winds were reaching out to 60 miles of the eye, but tropical storm winds extended outward from the center to 195 miles.
The greatest risk Humberto poses through Monday will be to marine interests due to massive seas of 40-60 feet likely near the center.
In comparison to Gabrielle, which passed about 175 miles to the east of Bermuda with only breezy conditions and rough seas, impacts in Bermuda will be more significant with Humberto. Gabrielle was smaller in overall size, compared to what Humberto has already become.
Conditions will deteriorate in Bermuda on Tuesday and may continue into Wednesday with strong wind gusts, squally rain, strong rip currents and massive seas outside of the islands' reefs.
Should Humberto's track shift farther to the east by 50-75 miles, then much more severe conditions could occur in Bermuda. Correspondingly, should Humberto's track end up being farther to the west by roughly the same distance, conditions only bordering on tropical storm force winds and some rain squalls would be likely.
In either case, surf will be hazardous for swimmers, and seas will be dangerous for both small and large crafts in the vicinity.
Humberto's intense nature could pull on Tropical Storm Imelda, which will bring heavy rain, flooding, wind and coastal erosion to part of the southeastern coast of the United States for the upcoming week. Should Humberto pull on Imelda just a bit, less intense rain and wind might occur along the southern Atlantic Coast of the U.S., with the storm tracking offshore rather than nearing the coast.
Humberto, along with Imelda, will contribute to rough seas and hazardous surf along much of the U.S. Atlantic Coast for much of this week.
Interests in Bermuda need to monitor Imelda
There has been a critical development with the track of Tropical Storm Imelda. Later next week, steering currents and a tug from the departing Humberto are forecast to guide Imelda eastward on a path that could take it very close to Bermuda, potentially as a hurricane.
The dashed red line represents AccuWeather meteorologists’ forecast path for the eye of Imelda. 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.
This could bring more substantial rain, wind and seas to the islands, when compared to Humberto.
