Former Hurricane Frank weakened to a tropical storm over the Eastern North Pacific Ocean west of Baja California on Monday morning. At 5:00 a.m. EDT on Monday the center of Tropical Storm Frank was located at latitude 21.7°N and longitude 121.5°W which put it about 745 miles (1200 km) west of the southern tip of Baja California. Frank was moving toward the northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 988 mb.
Former Hurricane Frank weakened to a tropical storm on Monday morning as it moved over cooler water in the Eastern North Pacific Ocean west of Baja California. Tropical Storm Frank was moving over water where the Sea Surface Temperatures are near 22˚C. Frank was unable to extract enough energy from the cooler water to maintain its intensity and the circulation weakened. The air over the cooler water was more stable and clouds were unable to rise as high into the atmosphere. The bands of thunderstorms weakened. Some drier, more stable air wrapped around the southern side of Frank’s circulation and the bands in that part of the tropical storm consisted primarily of showers and lower clouds. Tropical Storm Frank was still producing a large area of tropical storm force winds. Winds to tropical storm force extended out 140 miles (220 km) from the center of Frank.
Tropical Storm Frank will move through an environment unfavorable for a tropical cyclone during the next few days. Frank will move over water that is even colder than the water it is currently over. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Frank will weaken gradually during the next few days.
Tropical Storm Frank will move around the western part of a high pressure system over northern Mexico. The high pressure system will steer Frank toward the northwest during the next 36 hours. On its anticipated track Tropical Storm Frank will remain far to the west of Baja California.
Elsewhere over the Eastern North Pacific Ocean, Tropical Depression Georgette stalled west-southwest of Tropical Storm Frank. At 5:00 a.m. EDT on Monday the center of Tropical Depression Georgette was located at latitude 12.8°N and longitude 130.2°W which put it about 1505 miles (2420 km) west-southwest of the southern tip of Baja California. Georgette was moving toward the west at 2 m.p.h. (3 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1006 mb.
