Hurricane Norma Approaches Baja California

Hurricane Norma approached the southern end of Baja California on Friday afternoon. At 5:00 p.m. EDT on Friday the center of Hurricane Norma was located at latitude 20.1°N and longitude 109.8°W which put it about 195 miles (310 km) south of Cabo San Lucas, Mexico. Norma was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h). The minimum surface pressure was 955 mb.

A Hurricane Warning was in effect for the portion of the coast from Todos Santos to Los Barriles, Mexico. The Hurricane Warning included Cabo San Lucas. Tropical Storm Warnings were in effect for the portions of the coast from Todos Santos to Santa Fe, Mexico and from Los Barriles to San Evaristo, Mexico. A Tropical Storm Watch was in effect for Las Islas Marias. A Tropical Storm Watch was also in effect for the portion of the coast from Topolobampo to Bahia Tempehuaya, Mexico.

Hurricane Norma was still a major hurricane as it approached the southern end of Baja California on Friday afternoon. A circular eye with a diameter of 18 miles (30 km) was at the center of Norma’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. 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 35 miles (55 km) from the center of Hurricane Norma. Winds to tropical storm force extended out 160 miles (260 km) from the center of Norma’s circulation. The Hurricane Intensity Index (HII) was 22.1. The Hurricane Size Index (HSI) was 13.3 and the Hurricane Wind Intensity Size Index (HWISI) was 35.4. Hurricane Norma was similar in size and intensity to Hurricane Delta when Delta hit Louisiana in 2020.

Hurricane Norma will move through an environment unfavorable for intensification during the next 24 hours. Norma will move over water where the Sea Surface Temperatures are near 29°C. However, an upper level trough west of Baja California will produce southwesterly winds that will blow toward the top of Norma’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will cause Hurricane Norma will to weaken during the next 24 hours.

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 will approach the southern end of Baja California on Saturday morning. Norma will bring strong, gusty winds and locally heavy rain to the southern end of Baja California. Heavy rain is likely to cause flash floods in some locations. Hurricane Norma could cause a storm surge of up to 10 feet (3 meters along the coast at the southern end of Baja California.

Norma Prompts Hurricane Warning for Baja California

The potential risk posed by Hurricane Norma prompted the issuance of a Hurricane Warning for the southern part of Baja California. At 11:00 p.m. EDT on Thursday the center of Hurricane Norma was located at latitude 18.2°N and longitude 108.1°W which put it about 345 miles (555 km) south-southeast of Cabo San Lucas, Mexico.

The minimum surface pressure was 948 mb.

A Hurricane Warning was in effect for the portion of the coast from Todos Santos to Los Barriles, Mexico. The Hurricane Warning included Cabo San Lucas. A Tropical Storm Watch was in effect for Los Islas Marias. Tropical Storm Watches were also in effect for the portions of the coast from Todos Santos to Santa Fe, Mexico and from Los Barriles to La Paz, Mexico.

Hurricane Norma weakened slowly on Thursday evening. An upper level trough west of Baja California was producing southwesterly winds that were blowing toward the top of Norma’s circulation. Those winds were causing the vertical wind shear to increase. The eye at the center of Hurricane Norma was less distinct on satellite images. Bands of showers and thunderstorms were revolving around the core of Norma’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Norma. Winds to tropical storm force extended out 150 miles (240 km) from the center of Norma’s circulation. The Hurricane Intensity Index (HII) for Hurricane Norma was 22.1. The Hurricane Size Index (HSI) was 12.5 and the Hurricane Wind Intensity Size Index (HWISI) was 34.6. Hurricane Norma was similar in size and intensity to Hurricane Delta when Delta hit southwest Louisiana in 2020.

Hurricane Norma will move through an environment unfavorable for intensification during the next 24 hours. Norma will move over water where the Sea Surface Temperatures are near 29°C. However, the upper level trough west of Baja California will continue to produce southwesterly winds that will blow toward the top of Norma’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will cause Hurricane Norma will to weaken during the next 24 hours.

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 Friday night. Norma will bring strong winds and locally heavy rain to the southern end of Baja California. Heavy rain is likely to cause flash floods in some locations.

Tropical Storm Warnings were in effect for the portions of the coast from Manzanillo to Punta Mita, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Punta Mita to San Blas, Mexico. A Tropical Storm Watch was also in effect for Las Islas Marias.

The center of former Hurricane Beatriz made a landfall near Punta San Telmo, Mexico during Friday night. When the center of Beatriz made landfall, it significantly disrupted the inner core of Beatriz’ circulation. The disruption of the inner core caused Beatriz to weaken to a tropical storm. The distribution of thunderstorms in Tropical Storm Beatriz became asymmetrical after if made landfall. Most of the thunderstorms were occurring in bands in the western half of Beatriz’ circulation. Bands in the eastern part of the tropical storm consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 80 miles (130 km) from the center of Tropical Storm Beatriz.

Former Hurricane Beatriz brought gusty winds and locally heavy rain to the west coast of Mexico from Punta San Telmo to Cabo Corrientes during Friday night. The heaviest rain fell along the coast in Michoacan, Colima and Jalisco.

Tropical Storm Beatriz will move through an environment that will be only marginally favorable for intensification during the next 36 hours. Beatriz will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the southern part of an upper level ridge over northern Mexico. The upper level ridge will produce easterly winds that will blow toward the top of Beatriz’ circulation. Those winds will cause the wind shear to increase. Since Tropical Storm Beatriz is near the west coast of Mexico, it’s circulation will pull drier air into the eastern and northern parts of Beatriz. The drier air will inhibit the formation of thunderstorms in those parts of the circulation. Since the inner core of Tropical Storm Beatriz was disrupted when it moved over the coast, Beatriz is likely to continue to weaken during the next 36 hours.

The upper level ridge over northern Mexico will steer Tropical Storm Beatriz toward the northwest during the next 36 hours. On its anticipated track, Tropical Storm Beatriz will gradually move away from the west coast of Mexico. The gusty winds and locally heavy rain in Jalisco will gradually diminish on Saturday. Beatriz could move southeast of Baja California on Sunday.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Adrian weakened south of Baja California. At 5:00 a.m. EDT on Saturday the center of Hurricane Adrian was located at latitude 18.1°N and longitude 114.0°W which put it about 425 miles (685 km) southwest of the southern tip of Baja California. Adrian was moving toward the west-northwest at 7 m.p.h. (11 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 983 mb.

Beatriz Rapidly Intensifies to a Hurricane

Former Tropical Storm Beatriz rapidly intensified to a hurricane over the Eastern North Pacific Ocean south of Lazaro Cardenas, Mexico on Friday morning. At 11:00 a.m. EDT on Friday the center of Hurricane Beatriz was located at latitude 17.3°N and longitude 102.3°W which put it about 50 miles (80 km) south of Lazaro Cardenas, Mexico. Beatriz was moving toward the northwest at 13 m.p.h. (20 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 991 mb.

A Hurricane Warning was in effect for the portion of the coast from Zihuatenajo to Cabo Corrientes, Mexico. The Hurricane Warning included Manzanillo. A Hurricane Watch was in effect for the portion of the coast from Cabo Corrientes to Punta Mita, Mexico.

A Tropical Storm Watch was in effect for the portion of the coast from Punta Mita to San Blas, Mexico. A Tropical Storm Watch was also in effect for Las Islas Marias.

Former Tropical Storm Beatriz rapidly intensified to a hurricane on Friday morning. The inner end of a rainband wrapped around the center of Beatriz’ circulation. Visible and microwave satellite images showed that an eye was forming at the center of Hurricane Beatriz. Bands of showers and thunderstorms were revolving around the core of Beatriz. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Beatriz was small. Winds to hurricane force extended out 15 miles (25 km) in the northeastern quadrant of Beatriz’ circulation. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Hurricane Beatriz will move through an environment favorable for intensification during the next 12 hours. Beatriz will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southwestern part of an upper level ridge over Mexico and the southern U.S. The upper level ridge will produce easterly winds that will blow toward the top of Hurricane Beatriz. However, the winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Hurricane Beatriz is likely to intensify during the next 12 hours. Beatriz will be near the coast of Mexico on Saturday. If the core of Hurricane Beatriz remains over the Eastern North Pacific Ocean, then it will be in an environment favorable for intensification. If Beatriz moves over land on Saturday, it will weaken quickly.

The upper level ridge over Mexico and the southern U.S. will steer Hurricane Beatriz toward the northwest during the next 24 hours. On its anticipated track, Hurricane Beatriz will move very close to the coast of Mexico. The center of Beatriz could be near Manzanillo by Friday night. Beatriz could make landfall near Manzanillo or the center of circulation could pass just to the west of Manzanillo. Bands in the northern side of Hurricane Beatriz will bring strong winds and locally heavy rain to parts of the west coast of Mexico. Beatriz will bring strong winds and locally heavy rain to Guerrero, Michoacan, Colima and Jalisco. Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Adrian intensified south-southwest of Baja California. At 11:00 a.m. EDT on Friday the center of Hurricane Adrian was located at latitude 17.3°N and longitude 112.2°W which put it about 415 miles (665 km) south-southwest of the southern tip of Baja California. Adrian was moving toward the northwest 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 center of Hurricane Roslyn made landfall on the west coast of Mexico north of San Blas on Sunday morning. Roslyn was a major hurricane at the time of landfall. Winds to hurricane force extended out 25 miles (40 km) from the center of Roslyn’s circulation. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation. The Hurricane Intensity Index (HII) was 22.1. The Hurricane Size Index (HSI) was 8.5 and the Hurricane Wind Intensity Size Index (HWISI) was 30.6. Hurricane Roslyn was capable of causing localized major damage.

An upper level trough west of Baja California and a high pressure system over Mexico will steer Hurricane Roslyn quickly toward the northeast on Sunday. Roslyn will bring strong winds and drop locally heavy rain over Nayarit. Strong winds are likely to cause damage and electricity outages. Hurricane Roslyn will weaken steadily as it moves inland over western Mexico. Even though it will weaken, Roslyn could also drop locally heavy rain over southern Durango. Heavy rain could cause flash floods in some parts of Nayarit and southern Durango.
