Tropical Storm Humberto could become a first hurricane of the 2013 Atlantic hurricane season. It could also be the latest first hurricane in the season since the records began in early 60's. September usually brings 2-3 hurricanes.

Humberto is currently located in Eastern Atlantic, about 400 km west of Cape Verde Islands and it's reaching wind speed of 110 km/h (70 mph) at the moment.
According to latest public advisory issued by National Hurricane Center (NHC) at 21:00 UTC, the system was moving northwestward at speed of 13 km/h (8 mph). Tropical storm force winds extend outward up to 150 km (90 miles) from the center. The central minimum pressure is 993 mb (29.32 inches).

The system is entering an area of the atmosphere with low disruptive winds Humberto should maintain hurricane strength for a couple of days before vertical shear increases and the storm reaches a more hostile thermodynamic environment. The system is forecasted to turn sharply westward by the end of the week when a mid-level anticyclone rebuilds northwest of the Azores.

NASA's TRMM satellite saw heavy rain falling at a rate of 2 inches/50 mm per hour, south of Tropical Storm Humberto's center as it continues to strengthen in the Eastern Atlantic.
