Tropical Depression Lester Brings Rain to Southern Mexico

Tropical Depression Lester brought rain to southern Mexico on Saturday afternoon. At 2:00 p.m. EDT on Saturday the center of Tropical Depression Lester was located at latitude 16.5°N and longitude 98.5°W which put it about 85 miles (135 km) east-southeast of Acapulco, Mexico. Lester was moving toward the north at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1009 mb.

Former Tropical Storm Lester quickly weakened to a tropical depression after the center made landfall on the coast of Mexico east of Acapulco. The government of Mexico discontinued the tropical storm warnings and watches for the coast. Tropical Depression Lester is forecast to dissipate quickly as it moves farther inland over Mexico. Even though Lester will weaken quickly, bands in the eastern side of Lester’s circulation will drop locally heavy rain over parts of Guerrero and Oaxaca. Heavy rain could cause flash floods in some locations.

Hurricane Rick Makes Landfall on West Coast of Mexico

Hurricane Rick made landfall on the west coast of Mexico on Monday morning. At 8:00 a.m. EDT on Monday the center of Hurricane Rick was located at latitude 18.2°N and longitude 102.1°W which put it about 15 miles (25 km) north-northeast of Lazaro Cardenas, Mexico. Rick was moving toward the north at 8 m.p.h. (13 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 977 mb.

A Hurricane Warning was in effect for the portion of the coast from Tecpan De Galeana to Punta San Telmo, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Punta San Telmo to Manzanillo and from Tecpan de Galeana to Acapulco, Mexico.

Hurricane Rick made landfall on the west coast of Mexico between Zihuatenajo and Lazaro Cardenas on Monday morning. Rick intensified before it made landfall. The maximum sustained wind speed increased to 105 m.p.h. (165 km/h) which made Rick a Category 2 hurricane on the Saffir-Simpson Scale. Even though Hurricane Rick intensified, the circulation remained relative small. Winds to hurricane force extended out 25 miles (40 km) from the center of Rick. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

The Hurricane Intensity Index (HII) for Hurricane Rick was 17.8. The Hurricane Size Index (HSI) was 8.2 and the Hurricane Wind Intensity Size Index (HWISI) was 26.0. Hurricane Rick was capable of causing regionalized serious damage.

Hurricane Rick was bringing strong winds and locally heavy rain to the portion of the coast between Lazaro Cardenas and Zihuatenajo. There were reports of damage in Ixtapa. Winds blowing water toward the coast were causing a storm surge. Heavy rain was falling over parts of Guerrero and Michoacan. The heavy rain could cause flash floods in some locations. Hurricane Rick will weaken steadily now that the center is inland. However, heavy rain will spread over inland sections of Guerrero and Michoacan and flash floods could occur in those areas.

Hurricane Rick Moves Toward Mexico

Hurricane Rick moved slowly toward the west coast of Mexico on Sunday afternoon. At 2:00 p.m. EDT on Sunday the center of Hurricane Rick was located at latitude 16.4°N and longitude 101.7°W which put it about 85 miles (135 km) south of Zihuatenajo, Mexico. Rick was moving toward the north at 6 m.p.h. (10 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 980 mb.

A Hurricane Warning was in effect for the portion of the coast from Tecpan De Galeana to Punta San Telmo, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Punta San Telmo to Manzanillo and from Tecpan de Galeana to Acapulco, Mexico.

The intensity of Hurricane Rick was steady during the past few hours. The inner core of Rick’s circulation was not as well organized as it was on Saturday afternoon. There were breaks in the ring of thunderstorms surrounding the center of Hurricane Rick. Storms near the center of circulation continued to generate upper level divergence that pumped mass away from the hurricane. Bands of showers and thunderstorms revolved around the center of Rick. The circulation around Hurricane Rick was small. Winds to hurricane force extended out 15 miles (25 km) from the center of Rick. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Hurricane Rick will move through an environment favorable for intensification during the next 12 hours. Rick will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Rick could intensify during the next 12 hours. However, the less organized core of Rick will limit intensification. An upper level trough near the west coast of the U.S. will produce strong southwesterly winds that will blow toward the top of Rick’s circulation on Monday. Those winds will cause vertical wind shear and the shear could cause Hurricane Rick to weaken as it nears the coast of Mexico.

Hurricane Rick will move around the western part of a high pressure system over Mexico during the next 24 hours. A large upper level trough near the west coast of the U.S. will cause the high pressure system to weaken. As the high pressure system weakens, the southern part of the upper level trough will steer Rick toward the north. On its anticipated track Hurricane Rick could make landfall on the west coast of Mexico on Sunday night. Hurricane Rick will bring strong winds and locally heavy rain to the portion of the coast near Zihuatanejo. Heavy rain could cause flash floods in parts of Guerrero and Michoacan on Sunday night and Monday.

Rick Rapidly Intensifies to a Hurricane South of Mexico

Former Tropical Storm Rick rapidly intensified to a hurricane south of Mexico early on Saturday. At 8:00 a.m. EDT on Saturday the center of Hurricane Rick was located at latitude 14.3°N and longitude 101.5°W which put it about 235 miles (380 km) south of Zihuatenajo, Mexico. Rick was moving toward the north-northwest at 6 m.p.h. (10 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 Hurricane Watch was in effect for the portion of the coast from Tecpan De Galeana to Punta San Telmo, Mexico. Tropical Storm Watches were in effect for the portions of the coast from Punta San Telmo to Manzanillo and from Tecpan de Galeana to Acapulco, Mexico.

Former Tropical Storm Rick intensified rapidly during Friday night and it strengthened to a hurricane early on Saturday. A small eye formed at the center of Hurricane Rick. 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 core of Rick’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane. The removal of mass allowed the surface pressure to decrease quickly. The circulation around Hurricane Rick was small. Winds to hurricane force extended out 15 miles (25 km) from the center of Rick. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Hurricane Rick will move through an environment very favorable for intensification during the next 24 hours. Rick will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Rick will likely continue to intensify rapidly during the next 24 hours. Rick could strengthen to a major hurricane on Sunday.

Hurricane Rick will move around the western part of a high pressure system over Mexico during the next 24 hours. A large upper level trough approaching the west coast of the U.S. will cause the high pressure system to weaken during the weekend. As the high pressure system weakens, the southern part of the upper level trough will steer Rick toward the north. On its anticipated track Hurricane Rick could approach the west coast of Mexico by later on Sunday. Rick could be a major hurricane when it approaches the coast of Mexico. The Hurricane and Tropical Storm Watches are likely to be changed to warnings later today. Hurricane Rick could bring strong winds and heavy rain to Guerrero and Michoacan on Sunday night and Monday.

Tropical Storm Dolores Strengthens Near Mexico

Tropical Storm Dolores strengthened near the west coast of Mexico on Saturday morning. At 8:00 a.m. EDT on Saturday the center of Tropical Storm Dolores was located at latitude 17.9°N and longitude 103.4°W which put it about 95 miles (155 km) southeast of Manzanillo, Mexico. Dolores was moving toward the north-northwest at 13 m.p.h. (20 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 994 mb.

A Hurricane Watch was in effect for the portion of the coast from Lazaro Cardenas to Cabo Corrientes, Mexico. A Tropical Storm Warning was in effect for the portion of the coast from Lazaro Cardenas to Cabo Corrientes, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Cabo Corrientes to Escuinapa, Mexico.

The circulation around Tropical Storm Dolores exhibited much more organization on Saturday morning. The inner end of a rainband wrapped around the western, southern and eastern sides of the center of circulation. An eye appeared to be forming at the center of Dolores. Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. The circulation around Tropical Storm Dolores was relatively small. Winds to tropical storm force extended out 100 miles (160 km) in the northern half of the circulation. Winds to tropical storm force extended out 60 miles (95 km) in the southern half of Dolores.

Tropical Storm Dolores will move through an environment favorable for intensification during the next few hours. Dolores will move over an area where the Sea Surface Temperatures are near 30°C. It will move under the western part of an upper level ridge over southern Mexico and the Eastern North Pacific Ocean. The upper level winds are weak in that portion of the ridge and there will be little vertical wind shear. Tropical Storm Dolores could strengthen to a hurricane before it makes landfall.

Tropical Storm Dolores will move around the western end of a small high pressure system over southern Mexico. The high pressure system will steer Dolores toward the north-northwest during the next 24 hours. On its anticipated track Tropical Storm Dolores could make landfall on the coast of Mexico east of Manzanillo in a few hours. Dolores could be a hurricane when it makes landfall. Tropical Storm Dolores will bring gusty winds to the region near and to the east of Manzanillo. It could cause a storm surge of up to seven feet (two meters) in some locations on the coast. Bands on the northern side of Tropical Storm Dolores could drop heavy rain on parts of western Guerrero, Colima and Jalisco. Heavy rain could cause flash floods in some locations.

Tropical Storm Narda Forms South of Mexico

Tropical Storm Narda formed south of Mexico late on Saturday.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Narda was located at latitude 15.4°N and longitude 100.6°W which put it about 115 miles south-southwest of Acapulco, Mexico.  Narda was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 40 m.p.h. (15 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1000 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Acapulco to Cabo Corrientes, Mexico.

An area of low pressure exhibited more organization late on Saturday and the National Hurricane Center designated the system as Tropical Storm Narda.  A low level center of circulation formed within the area of low pressure.  Bands of showers and thunderstorms developed and began to revolve around the center of circulation.  Many of the stronger thunderstorms were in bands in the western half of the circulation.  Bands in the eastern half of the circulation contained more showers and lower clouds.  An area of winds to tropical storm force was occurring about 120 miles (195 km) southeast of the center of circulation.

Tropical Storm Narda will move through an environment only marginally favorable for intensification on Sunday.  Narda will move over water where the Sea Surface Temperature is near 29°C.  However, an upper level ridge over Mexico will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause moderate vertical wind shear which will inhibit intensification.  In addition, the circulation could draw drier air into the northern portion of the tropical storm.  Tropical Storm Narda is not likely to strengthen much during the next 12 to 24 hours.

The ridge over Mexico will steer Tropical Storm Narda toward the northwest during the next several days.  On its anticipated track Tropical Storm Narda will approach the coast of Mexico near Lazaro Cardenas in about 12 hours.  Narda will move along the coast toward Cabo Corrientes.  Tropical Storm Narda could drop locally heavy rain in parts of Guerrero, Michoacan, Colima and Jalisco.  The rain could cause flash floods in some locations.
