Lane Strengthens Into a Hurricane

Former Tropical Storm Lane strengthened into a hurricane on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Hurricane Lane was located at latitude 11.2°N and longitude 129.8°W which put it about 1780 miles (2865 km) east-southeast of Hilo, Hawaii.  Lane was moving toward the west-northwest at 15 m.p.h. (24 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 992 mb.

The circulation of Hurricane Lane became much better organized.  A primary rainband wrapped most of the way around the center of circulation and it could become an eyewall.  Several bands of showers and thunderstorms in the southern and eastern parts of the circulation were revolving around the core of Hurricane Lane.  Storms near the core were generating strong upper level divergence which was pumping mass away from the hurricane in all directions.  Winds to hurricane force extended out about 20 miles (30 km) from the center of circulation.  Winds to tropical storm force extended out about 60 miles (95 km) from the center.

Hurricane Lane will be moving through an environment that will be favorable for intensification during the next several days.  Lane will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Lane will intensify during the next 36 to 48 hours and it could intensify rapidly once a well developed eye forms.

Hurricane Lane will move south of the subtropical high over the Eastern North Pacific Ocean.  The high will steer Lane in a general west-northwesterly direction during the next few days.  On its anticipated track Hurricane Lane could be southeast of Hawaii by early next week.
