There are currently three named tropical cyclones in the Atlantic Basin…Hurricane Igor, Hurricane Julia and most recently Tropical Storm Karl. Both Igor and Julia appear to have reached their max intensity as major category 4 hurricanes. Forecasts call for favorable conditions the next few days which may sustain both at major hurricane status until increased wind shear and a turn to the northwest into cooler waters begins to weaken both tropical systems. Both these storms are being steered by an area of high pressure over the eastern Atlantic as many hurricanes in the Atlantic are.

Tropical Storm Karl has made its initial landfall after recently developing in the past 24 hours off the Yucatan Peninsula. This storm is expected to reemerge in the Gulf of Mexico and may briefly become a category 1 hurricane before making landfall a second time south of the US border in Mexico.
