Former Tropical Storm Kirk intensified to a hurricane over the Atlantic Ocean west of the Cabo Verde Islands on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Hurricane Kirk was located at latitude 16.2°N and longitude 40.1°W which put the center about 1070 miles (1720 km) west of the Cabo Verde Islands.  Kirk was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 986 mb.

Former Tropical Storm Kirk intensified to a hurricane on Tuesday.  The inner end of a rainband wrapped around the center of KIrk’s circulation and an eye appeared to be forming at the center of Hurricane Kirk.  Bands of showers and thunderstorms were revolving around the core of Hurricane Kirk.  Storm near the center of Kirk’s circulation generated upper level divergence that pumped mass away from the hurricane.

The size of the circulation around Hurricane Kirk increased on Tuesday.  Winds to hurricane force extended out 30 miles (50 km) in the northeastern quadrant of Kirk’s circulation.  Winds to tropical storm force extended out 200 miles (320 km) from the center of Hurricane Kirk.

Hurricane Kirk will move through an environment favorable for intensification during the next 24 hours.  Kirk will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over the eastern Atlantic Ocean.  The winds are weak near the middle of the upper level ridge and there will be little vertical wind shear. Hurricane Kirk will intensify during the next 24 hours.  Kirk is likely to strengthen to a major hurricane later this week.

Hurricane Kirk will move around the southwestern part of a subtropical high pressure system over the Atlantic Ocean.  The high pressure system will steer Kirk toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Kirk will move farther away from the Cabo Verde Islands.
