Hurricane Linda Churns West

Hurricane Linda churned westward over the Eastern North Pacific Ocean on Sunday. At 5:00 p.m. EDT on Sunday the center of Hurricane Linda was located at latitude 18.8°N and longitude 121.2°W which put it about 780 miles (1260 km) west-southwest of the southern tip of Baja California. Linda was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 969 mb.

Hurricane Linda assumed a symmetrical shape on Sunday that is sometimes called an annular hurricane. A large, circular eye with a diameter of 40 miles (65 km) was at the center of Linda. The eye was surround by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Several short bands of showers and thunderstorms were revolving around the core of Hurricane Lida. Storms near the core of Linda generated upper level divergence that pumped mass away from the hurricane.

The wind field around Hurricane Linda was also very symmetrical. Winds to hurricane force extended out 30 miles (50 km) from the center of Linda. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane was 19.2. The Hurricane Size Index (HSI) was 9.9 and the Hurricane Wind Intensity Size Index (HWISI) was 29.1.

Hurricane Linda will move through an environment unfavorable for a strong hurricane during the next few days. Linda will move over water where the Sea Surface Temperatures are near 25°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Cooler water will supply less energy for Hurricane Linda and it will weaken. However, symmetrical (annular) hurricanes tend to be nearly in balance with their environment. Since there will be little vertical wind shear, Hurricane Linda is likely to weaken very gradually.

Hurricane Linda will move south of a subtropical high pressure system over the Eastern North Pacific Ocean during the next few days. The high pressure system will steer Linda toward the west. On its anticipated track Hurricane Linda will continue to move toward the Central Pacific.
