Tropical Storm Norbert Develops Southwest of Mexico

Tropical Storm Norbert developed southwest of Mexico on Tuesday morning.  At 5: 00 a.m. EDT on Tuesday the center of Tropical Storm Norbert was located at latitude 13.7°N and longitude 106.2°W which put it about 385 miles (625 km) south-southwest of Manzanillo, Mexico.  Norbert was moving toward the northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1002 mb.

The wind speed increased around a low pressure system southwest of Mexico on Tuesday morning and the National Hurricane Center designated the system as Tropical Storm Norbert.  More thunderstorms formed near the center of Norbert.  Storms near the center of circulation started to generate upper level divergence which pumped mass away to the northeast of the tropical storm.  Bands of showers and thunderstorms were developing outside the center of Norbert.  The circulation around Tropical Storm Norbert was small.  Winds to tropical storm force extended out 25 miles from the center of circulation.

Tropical Storm Norbert will be in an environment that is somewhat favorable for intensification.  Norbert will move over water where the Sea Surface Temperature is near 29°C.  A large upper level trough extends from northern Mexico over the Eastern North Pacific Ocean.  The trough will produce southwesterly winds which will blow toward the top of Tropical Storm Norbert.  Those winds will cause vertical wind shear and the shear will inhibit intensification.  Tropical Storm Norbert could strengthen if the shear is not too strong.

Tropical Storm Norbert will be in a region where the steering currents are weak..  Norbert is not likely to move very much during the next several days.  If Tropical Storm Norbert remains in the same location for more than a day, its winds will mix cooler water to the surface.  That would limit the energy Norbert could extract from the ocean, and the tropical storm could weaken.

Elsewhere over the Eastern North Pacific, Tropical Storm Marie continued to churn west away from Baja California.  At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Marie was located at latitude 21.7°W and longitude 134.3°W which put it about 1560 miles (2510 km) west of the southern tip of Baja California.  Marie was moving toward the west-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 1003 mb.

Hurricane Marie Weakens West of Baja California

Hurricane Marie weakened west of Baja California on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Hurricane Marie was located at latitude 19.5°N and longitude 127.9°W which put it about 1180 miles (1900 km) west of the southern tip of Baja California.  Marie was moving toward the northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (220 km/h).  The minimum surface pressure was 960 mb.

Hurricane Marie began to move over water where the Sea Surface Temperature was cooler than 26°C on Saturday evening.  Marie was unable to extract enough energy from the ocean to maintain its intensity.  The circulation around Hurricane Marie pulled cooler, more stable air around its southern side.  The rainbands in the southern half of Marie started to weaken.  The southern side of the eyewall weakened too.  Strong thunderstorms were still occurring in rainbands in the northern half of Hurricane Marie.  Winds to hurricane force extended out 30 miles (50 km) from the center of circulation.  Winds to tropical storm force extended out 150 miles (240 km) from the center.

Hurricane Marie will move around the western side of a ridge of high pressure over the southwestern U.S.  The high will steer Marie toward the north-northwest during the next few days.  Hurricane Marie will move over even cooler water during the next several days, which will cause it to weaken more quickly.  Marie could weaken to a tropical depression by the middle of next week.  Eventually, some of the moisture in Hurricane Marie could be transported over California by the end of next week.

Marie Strengthens into a Major Hurricane

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.

Marie Rapidly Strengthens Into a Hurricane

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.

Tropical Storm Marie Forms South of Baja California

Tropical Storm Marie formed south of Baja California on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Marie was located at latitude 13.6°N and longitude 109.5°W which put it about 645 miles (1035 km) south of the southern tip of Baja California.  Marie was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1005 mb.

More thunderstorms developed near the center of a small low pressure system south of Baja California on Tuesday afternoon and the National Hurricane Center designated the system as Tropical Storm Marie.  The circulation around Marie was still organizing.  More thunderstorms were forming around the center of Tropical Storm Marie.  Bands of showers and thunderstorms were also developing and the bands were revolving around the center of the tropical storm.  Storms near the center of Marie started to generate upper level divergence which began to pump mass away to the west of the tropical storm.  The circulation around the Tropical Storm Marie was small.  Winds to tropical storm force extended out 25 miles (40 km) from the center of circulation.

Tropical Storm Marie will move through an environment favorable for intensification during the next two to three days.  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.  Tropical Storm Marie could intensify into a hurricane within 36 hours.  Marie could strengthen more rapidly once an inner core with an eye and an eyewall forms.  Tropical Storm Marie could intensify into a major hurricane later this week.

Tropical Storm 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 several days.  On its anticipated track Tropical Storm Marie will move farther away from Baja California.
