Hurricane Frank continued to spin over the Eastern North Pacific Ocean southwest of Baja California on Saturday night. At 11:00 p.m. EDT on Saturday the center of Hurricane Frank was located at latitude 18.0°N and longitude 117.7°W which put it about 605 miles (975 km) west-southwest 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 90 m.p.h. (145 km/h) and and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 975 mb.

Hurricane Frank appeared to have concentric eyewalls for a time on Saturday afternoon. The inner end of a rainband wrapped around the original eye and eyewall. Microwave satellite images depicted a larger outer eyewall surrounding the original eye and eyewall. The inner eyewall weakened somewhat by Saturday night, but it still was present inside the larger outer eyewall. Storms near the core of Frank’s circulation generated upper level divergence that pumped mass away from the hurricane. The formation of concentric eyewalls caused the size of the circulation around Hurricane Frank to increase. Winds to hurricane force extended out 25 miles (40 km) from the center of Frank. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation.

Hurricane Frank will move through an environment that is somewhat favorable for intensification during the next 24 hours. Frank will move over water where the Sea Surface Temperatures are near 26˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Frank could intensify during the next 24 hours if it completes an eyewall replacement cycle. Frank is likely to weaken early next week when it moves over cooler water.

Hurricane Frank will move around the southwestern part of a high pressure system over northern Mexico and the Eastern North Pacific Ocean. The high pressure system will steer Frank toward the northwest during the next 24 hours. On its anticipated track Hurricane Frank will move parallel to the coast of Baja California, but Frank will remain far to the west of the coast.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Georgette was located west-southwest of Hurricane Frank. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Georgette was located at latitude 13.4°N and longitude 128.5°W which put it about 1385 miles (2225 km) west-southwest of the southern tip of Baja California. Georgette was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 999 mb.
