Norma Rapidly Intensifies to a Hurricane

Former Tropical Storm Norma rapidly intensified to a hurricane over the Eastern North Pacific Ocean south of Baja California on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Hurricane Norma was located at latitude 15.6°N and longitude 108.0°W which put it about 520 miles (835 km) south-southeast of Cabo San Lucas, Mexico. Norma was moving toward the north at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 984 mb.

Former Tropical Storm Norma rapidly intensified to a hurricane on Wednesday. The inner end of a rainband wrapped around the center of Norma’s circulation and an eye was forming at the center. Bands of showers and thunderstorms were revolving around the core of Hurricane Norma. Storms near the core generated upper level divergence that pumped mass away from the hurricane. Winds to hurricane force extended out 25 miles (40 km) in the eastern side of Norma’s circulation. Winds to tropical storm force extended out 140 miles (220 km) from the center of Hurricane Norma.

Hurricane Norma will move through an environment very favorable for intensification during the next 24 hours. Norma 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 shear. Hurricane Norma will intensify during the next 24 hours. Norma could intensify rapidly to a major hurricane on Thursday.

Hurricane Norma will move around the western part of a high pressure system over Mexico. The high pressure system will steer Norma toward the north during the next 24 hours. On its anticipated track, Hurricane Norma could approach the southern end of Baja California on Saturday. Norma is likely to be a hurricane when it approaches Baja California.
