Tropical Storm Marie formed over the Eastern North Pacific Ocean southwest of Mexico on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Marie was located at latitude 16.1°N and longitude 110.3°W which put the center about 470 miles (755 km) south of the southern tip of Baja California.  Marie was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 994 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Mexico strengthened on Tuesday and the U.S. National Hurricane Center designated the system as Tropical Storm Marie.

Tropical Storm Marie intensified steadily on Tuesday.  Numerous thunderstorms developed near the center of Marie’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Marie.  Storms near the center of Marie generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Marie was large.  Winds to tropical storm force extended out 185 miles (295 km) from the center of Marie’s circulation.

Tropical Storm Marie will move through an environment that will be favorable for intensification during the next 24 hours.  Marie will move over water where the Sea Surface Temperatures are near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind wind shear.  Tropical Storm Marie will intensify during the next 24 hours.  Marie could intensify rapidly at times.  Tropical Storm Marie will strengthen to a hurricane on Wednesday.

Tropical Storm Marie will move around the southwestern side of a high pressure system that is centered over the southwest U.S.  The high pressure system will steer Marie toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Marie will move southwest of Baja California.

Elsewhere, Hurricane Lowell rapidly intensified to a major hurricane south-southeast of Hawaii and Hurricane Karina continued to be Category 4 hurricane on the Saffir-Simpson Scale.

At 11:00 p.m. EDT on Tuesday the center of Hurricane Lowell was located at latitude 13.5°N and longitude 151.2°W which put the center about 500 miles (805 km) south-southeast Hilo, Hawaii.  Lowell was moving toward the west at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 953 mb.

At 11:00 p.m. EDT on Tuesday the center of Hurricane Karina was located at latitude 18.3°N and longitude 130.8°W which put the center about 1385 miles (2230 km) west of the southern tip of Baja California.  Karina was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (265 km/h).  The minimum surface pressure was 946 mb.
