Tropical Storm Norman Forms Southwest of Baja California

Tropical Storm Norman formed southwest of Baja California on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Norman was located at latitude 17.5°N and longitude 113.9°W which put it about 455 miles (730 km) southwest of the southern tip of Baja California.  Norman was moving toward west-northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1000 mb.

The circulation of Tropical Storm Norman organized quickly on Wednesday.  A distinct low level center of circulation developed in an area of thunderstorms southwest of Baja California and the National Hurricane Center designated the system as Tropical Storm Norman.  A primary rainband wrapped part of the way around the center of circulation.  Several other bands of showers and thunderstorms formed and began to revolve around the core of Norman.  Storms near the core started to generate strong upper level divergence which was pumping mass away from the tropical storm in all directions.

Tropical Storm Norman will be moving through an environment favorable for intensification during the next several days.  Norman will move over water where the Sea Surface Temperature is near 29°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Norman could intensify to a hurricane in the next 24 hours.  Once an eye forms and the inner core is full organized, Norman could intensify rapidly.  It could strengthen into a major hurricane later this week.

Tropical Storm Norman will move south of a subtropical ridge over the Eastern North Pacific during the next few days.  The ridge will steer Norman in a general westerly direction.  On its anticipated track Tropical Storm Norman will move toward the Central Pacific.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Miriam continued to move westward.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Miriam was located at latitude 14.1°N and longitude 137.4°W which put it about 1230 miles (1980 km) east of HIlo, Hawaii.  Miriam was moving toward the west at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 1000 mb.

Tropical Storm Miriam Forms Southwest of Baja California

Tropical Storm Miriam formed southwest of Baja California on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Miriam was located at latitude 13.2°N and longitude 125.3°W which put it about 1210 miles (1950 km) west-southwest of the southern tip of Baja California.  Miriam was moving toward the west at 13 m.p.h. (20 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 1004 mb.

The circulation of Tropical Storm Miriam organized quickly on Sunday morning.  Several bands of showers and thunderstorms developed and the bands began to revolve around the center of circulation.  Storms near the core of Miriam started to generate upper level divergence which was pumping mass away in all directions.

Tropical Storm Miriam will move through an environment favorable for intensification during the next several days.  Miriam will move over water where the Sea Surface Temperature is near 28°C.  It will move through an area where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Miriam could intensify into a hurricane on Monday.  Miriam could intensify rapidly once the inner core becomes fully organized and an eye develops at the center of circulation.

Tropical Storm Miriam will move south of the subtropical ridge over the Eastern North Pacific Ocean.  The ridge will steer Miriam in a general westerly direction during the next two or three days.  On its anticipated track Tropical Storm Miriam will move farther away from Baja California.
