Hurricane Marie strengthened into a major hurricane on Thursday.  At 11:00 p.m. EDT on Thursday the center of Hurricane Marie was located at latitude 15.6°N and longitude 122.1°W which put it about 940 miles (1515 km) west-southwest of the southern tip of Baja California.  Marie was moving toward the west-northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 957 mb.

The circulation around Hurricane Marie was very well organized on Thursday night.  There was a small circular eye with a diameter of 12 miles (19 km) at the center of Marie.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Marie.  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 20 miles (30 km) from the center of Marie.  Winds to tropical storm force extended out 125 miles (200 km) from the center.

Hurricane Marie will move through an environment favorable for intensification during the next 24 hours.  Marie will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Marie is likely to strengthen on Friday.  If a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could begin which would cause Marie to weaken.  Hurricane Marie will move over cooler water during the weekend.  Marie will extract less energy from the ocean which will cause the wind speed to decrease.

Hurricane Marie will move south of a ridge of high pressure over the southwestern U.S. and Eastern North Pacific Ocean.  The high will steer Marie toward the west-northwest during the next several days.  On its anticipated track Hurricane Marie will move farther away from Baja California.

Former Tropical Storm Marie rapidly strengthened into a hurricane on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Hurricane Marie was located at latitude 14.3°N and longitude 115.1°W which put it about 685 miles (1100 km) south-southwest of the southern tip of Baja California.  Marie was moving toward the west at 16 m.p.h. (26 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 988 mb.

The circulation around Hurricane Marie exhibited much greater organization on Wednesday afternoon.  The inner end of a rainband wrapped entirely around the center of Marie.  Other bands of showers and thunderstorms were revolving around the core of Hurricane Marie.  Storms near the core generated upper level divergence which pumped mass away to the west of the hurricane.  The circulation around Marie was small.  Winds to hurricane force only extended out 15 miles (25 km) from the center of circulation.  Winds to tropical storm force only extended out 60 miles from the center.

Hurricane Marie will move through an environment favorable for intensification during the next 48 hours.  Marie will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level wind are weak and there will be little vertical wind shear.  Hurricane Marie will continue to strengthen and it could intensify rapidly at time.  Marie could intensify into a major hurricane within 36 hours.

Hurricane Marie will move south of a ridge of high pressure over the southwestern U.S.  The high will steer Marie toward the west-northwest during the next few days.  On its anticipated track Hurricane Marie will move farther away Baja California.
