Hurricane Lorena Near Cabo San Lucas

Hurricane Lorena moved near Cabo San Lucas, Mexico on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Hurricane Lorena was located at latitude 23.2°N and longitude 109.3°W which put it about 45 miles (75 km) northeast of Cabo San Lucas, Mexico.  Lorena was nearly stationary.  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 987 mb.

A Hurricane Warning was in effect for the portion of the coast from La Paz to Puerto Cortes, Mexico.  A Hurricane Watch was in effect for the portion of the coast from La Paz to Santa Rosalia.  Tropical Storm Warnings were in effect from Puerto Cortes to Cabo San Lazaro and from La Paz to Santa Rosalia.  Tropical Storm Watches were in effect from Topolobampo to Guaymas and from Cabo San Lazaro to Puerto San Andresito.

The circulation around Hurricane Lorena strengthened quickly when it reached the very warm water at the southern end of the Gulf of Calfiornia.  A small circular eye developed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the compact inner core of Hurricane Lorena.  Winds to hurricane force extended out 15 miles (25 km) from the center of circulation.  Winds to tropical storm force extended out 45 miles (75 km) from the center.

The future intensity of Hurricane Lorena will depend entirely on its track.  If Hurricane Lorena moves over Baja California, it will weaken quickly when it moves over the mountains.  However, if the small circulation around Lorena remains over the very warm water in the Gulf of California, then the hurricane could strengthen further.  The numerical models have been trending toward keeping Hurricane Lorena over water for a longer period of time, but the center of the hurricane is very close to the southern end of Baja California.

Hurricane Lorena moved into a region where the steering currents are weak, which is why Lorena is nearly stationary.  The southern end of a trough over the western U.S. will try to steer Hurricane Lorena toward the north-northeast.  However, mountains in Baja California sometimes block westerly winds in the lower levels.  A slightly larger circulation around Tropical Storm Mario could pull Hurricane Lorena toward the west.  The future track of Hurricane Lorena is highly uncertain.  Hurricane Lorena could move over Baja California or it could move farther north into the Gulf of California.

The center of Tropical Storm Mario was located at latitude 18.0°N and longitude 110.0°W which put it about 340 miles (545 km) south of the southern tip of Baja California.  Mario was moving toward the north at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 992 mb.  The future of Tropical Storm Mario will depend on how much its circulation interacts with the circulation around Hurricane Lorena.  Mario is currently about 350 miles (565 km) south of Hurricane Lorena.
