The first hurricane of the 2013 season formed Wednesday morning in the eastern Atlantic Ocean but forecasters say it is probably no threat to land.
Hurricane Humberto missed by about six hours the record for the latest-forming first hurricane of the season.
In 2002, Hurricane Gustav set a record for latest-forming hurricane around 11 a.m. on Sept. 11.
Humberto was upgraded from a tropical storm around 5 a.m. when it reached maximum sustained wind speeds over 74 mph west of the Cape Verde Islands. It was projected to move northwest through the Atlantic for the rest of the week.
Humberto is forecast to peak with winds of 85 mph in 24 hours. Then it is expected to hit cooler waters and begin to weaken before it encounters wind shear and dry air that should further weaken it as it begins a west-northwest movement.
Tuesday marked the statistical peak of the hurricane season, the point at which most hurricanes are tracked.
Forecasters were monitoring several areas for development.
The reorganized Tropical Storm Gabrielle was moving northwest near Bermuda on Wednesday with sustained winds of 50 mph. It was projected to affect portions of eastern Canada later in the week.
Along the coast of the Yucatán Peninsula, the National Hurricane Center was tracking an area of low pressure projected to move into the Gulf of Mexico near the end of the week.
That system should move across the Yucatán Peninsula today and emerge into the Bay of Campeche on Thursday, where it has a good chance of becoming a named storm (Ingrid).
Most of the models then take it west-northwest into Mexico.
Lastly, forecasters were watching a broad area of low pressure about 700 miles east of the Leeward Islands. It was given only a slight chance of development.
