Tropical Storm Humberto was forecast to become the season's first hurricane some time Tuesday, while Tropical Storm Gabrielle reorganized and gained strength south of Bermuda.
Humberto formed near the Cape Verde Islands early Monday, battering the area with wind and rain throughout the day.
The storm gained speed as it moved west, and winds were at 65 mph early Tuesday morning; Category 1 hurricanes have wind speeds of at least 74 mph.
The storm was expected to move north this week.
Meanwhile, Tropical Storm Gabrielle, downgraded Friday to a tropical depression, had reformed south of Bermuda and was moving north with winds at 40 mph, once again earning its tropical storm classification.
Gabrielle was expected to bring rain to Bermuda Tuesday and could affect Novia Scotia and Newfoundland if it stays on its current path.
Tuesday marked the statistical peak of hurricane season, National Hurricane Center Meteorologist Dennis Feltgen said. Feltgen explained that over the last 100 years of data, Sept. 10 has averaged the highest number of hurricanes.
September 11 is another significant date in hurricane history: the latest date a season's first hurricane has formed since satellites have been tracking Atlantic weather patterns. That record was set by Hurricane Gustav in 2002. Tropical Storm Humberto is on track to claim the second latest date in modern history.
Bay News 9 Meteorologist Juli Marquez said although the first half of the season has been characterized by tropical storms, the Tampa Bay area remains prone to developments moving forward.
"We can't let our guard down yet," Marquez said Tuesday.
The National Hurricane Center also was tracking a tropical depression in the Caribbean that it predicted early Tuesday would move west into the Bay of Campeche by Thursday morning.
The system had a high chance of becoming a tropical storm over the next five days, according to the National Hurricane Center.
