Hurricane Lorena Moves Toward Baja California

Hurricane Lorena was moving toward Baja California on Wednesday evening.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Lorena was located at latitude 23.4°N and longitude 113.2°W which put the center about 110 miles (175 km) south-southwest of Cabo San Lazaro, Mexico.  Lorena was moving toward the northwest at 12 m.p.h. (19 km/h).  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 981 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Santa Fe to Punta Eugenia, Mexico.

A Tropical Storm Watch is in effect for the portion of the coast from Todos Santos to Sante Fe, Mexico.  A Tropical Storm Watch is in effect for the portion of the coast from Santa Rosalia to Bahia de Los Angeles, Mexico.

Hurricane Lorena strengthened a little more on Wednesday.  The inner end of a rainband wrapped around the center of Lorena’s circulation.  However, an eye was not visible on satellite images.  Bands of showers and thunderstorms were revolving around the center of Hurricane Lorena.  Storms near the center of Lorena generated upper level divergence that pumped mass away to the northeast of the hurricane.

The circulation around Hurricane Lorena was small.  Winds to hurricane force extended out 20 miles (30 km) in the northeastern quadrant of Lorena’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Hurricane Lorena.

Hurricane Lorena will move through an environment that will become unfavorable for intensification during the next 24 hours.  Lorena will move over water where the Sea Surface Temperatures are near 25°C.  It will move under the southeastern part of an upper level trough that is west of Baja California.  The upper level trough will produce southwesterly winds that will blow toward the top of Lorena’s circulation.  Those winds will cause the vertical wind shear to increase.  The combination of cooler Sea Surface Temperatures and more vertical wind shear will cause Hurricane Lorena to weaken on Thursday.

Hurricane Lorena will move around the western end of a high pressure system that is over Mexico.  The high pressure system will steer Lorena toward the north during the next 24 hours.  The upper level trough that is west of Baja California will steer Lorena toward the northeast later on Thursday.  On its anticipated track, Hurricane Lorena will approach the coast of Baja California between Cabo San Lazaro and Punta Eugenia on Friday.

Hurricane Lorena will weaken to a tropical storm before it reaches the coast of Baja California.  Lorena will bring strong winds and locally heavy rain to parts of Baja California.  Heavy rain could cause flash floods in some locations.

Elsewhere, Hurricane Kiko strengthened to a Category 4 hurricane on the Saffir-Simpson Scale far to the east-southeast of Hawaii.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Kiko was located at latitude 13.8°N and longitude 132.3°W which put the center about 1560 miles (2510 km) east-southeast of Hilo Hawaii.  Kiko was moving toward the west at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 145 m.p.h. (235 km/h) and there were wind gusts to 170 m.p.h. (275 km/h).  The minimum surface pressure was 944 mb.

Lorena Intensifies to a Hurricane

Former Tropical Storm Lorena intensified to a hurricane over the Eastern North Pacific Ocean south of Baja California on Tuesday night.  The government of Mexico issued a Tropical Storm Warning for a portion of the coast of Baja California.  At 8:00 a.m. EDT on Wednesday the center of Hurricane Lorena was located at latitude 21.9°N and longitude 111.1°W which put the center about 105 miles (165 km) southwest of Cabo San Lucas, Mexico.  Lorena was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 990 mb.

A Tropical Storm Warning was in effect for a portion of the coast from Santa Fe to Cabo San Lazaro, Mexico.

A Tropical Storm Watch was in effect for the portion of the coast from Cabo San Lucas to Santa Fe, Mexico.  A Tropical Storm Watch was in effect for the portion of the coast from Cabo San Lazaro to Punta Abreojos, Mexico.

Former Tropical Storm Lorena intensified to a hurricane on Tuesday night.  The inner end of a rainband wrapped part of the way around the center of Lorena’s circulation.  A small eye appeared to be forming at the center of Hurricane Lorena.  Bands of showers and thunderstorms were revolving around the center of Lorena’s circulation.  Storms near the center of Lorena generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The circulation around Hurricane Lorena was small.  Winds to hurricane force extended out 15 miles (25 km) in the northeastern quadrant of Lorena’s circulation.  Winds to tropical storm force extended out 60 miles (95 km) from the center of Hurricane Lorena.

Hurricane Lorena will move through an environment favorable for intensification during the next 24 hours.  Lorena will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the western part of the axis of an upper level ridge over Mexico.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Hurricane Lorena will intensify during the next 24 hours.  Lorena could intensify rapidly at times on Wednesday.

Hurricane Lorena will move around the western end of a high pressure system over Mexico.  The high pressure system will steer Lorena toward the northwest during the next 24 hours.  Lorena is expected to move toward the north on Thursday.  On it anticipated track, Hurricane Lorena could approach the coast of Baja California between Cabo San Lazaro and Punta Eugenia on Friday.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Kiko continued to churn toward the west.  At 5:00 a.m. EDT on Wednesday the center of Hurricane Kiko was located at latitude 13.8°N and longitude 130.1°W which put the center about 1700 miles (2735 km) east Hilo Hawaii.  Kiko was moving toward the west at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 973 mb.

 

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.
