Hurricane Orlene Makes Landfall Southeast of Mazatlan

Hurricane Orlene made landfall on the west coast of Mexico southeast of Mazatlan on Monday morning. At 11:00 a.m. EDT on Monday the center of Hurricane Orlene was located at latitude 22.9°N and longitude 105.7°W which put it about 50 miles (80 km) east-southeast of Mazatlan, Mexico. Orlene was moving toward the north-northeast at 10 m.p.h. (16 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.

A Hurricane Warning was in effect for the portion of the coast from San Blas to Mazatlan, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Punta Mita to San Blas and from Mazatlan to Bahia Tempehuaya, Mexico.

Hurricane Orlene made landfall on the west coast of Mexico southeast of Mazatlan near Teacapan on Monday morning. Orlene was a small hurricane at the time of landfall. Winds to hurricane force extended out 20 miles (30 km) from the center of Orlene’s circulation. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Hurricane Orlene will weaken quickly as it moves inland. An upper level trough over northwestern Mexico will produce strong southwesterly winds that will blow toward the top of Orlene’s circulation. Those winds will cause strong vertical wind shear. The strong wind shear coupled with moving over land will cause Hurricane Orlene to weaken quickly.

Hurricane Orlene will bring strong, gusty winds and locally heavy rain to northern Nayarit and southern Sinaloa before it dissipates. Heavy rain could cause flash floods in some locations.

Hurricane Orlene Brings Wind and Rain to Las Islas Marias

Hurricane Orlene brought wind and rain to Las Islas Marias, Mexico on Sunday night. At 11:00 p.m. EDT on Sunday the center of Hurricane Orlene was located at latitude 21.4°N and longitude 106.5°W which put it about 10 miles (15 km) southwest of Las Islas Marias, Mexico. Orlene was moving toward the north-northeast 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 976 mb.

A Hurricane Warning was in effect for Las Islas Marias. A Hurricane Warning was in effect for the portion of the coast from San Blas to Mazatlan, Mexico. A Hurricane Watch was in effect for the portion of the coast from Playa Perula to San Blas, Mexico. A Hurricane Watch was in effect for the portion of the coast from Mazatlan to Bahia Tempehuaya, Mexico. A Tropical Storm Warning was in effect for the portion of the coast from Playa Perula to San Blas, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Manzanillo to Playa Perula, Mexico.

Hurricane Orlene weakened gradually on Sunday afternoon after it rapidly intensified to Category 4 on the Saffir-Simpson Scale earlier in the day. A circular eye with a diameter of 12 miles (19 km) was still present at the center of Hurricane Orlene. 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 core of Orlene’s circulation. Storms near the core generated upper level divergence that pumped mass away to the northeast of the hurricane.

The circulation around Hurricane Orlene was small. Winds to hurricane force extended out 20 miles (30 km) from the center of Orlene. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation. The Hurricane Intensity Index (HII) was 17.8. The Hurricane Size Index (HSI) was 6.8 and the Hurricane Wind Intensity Size Index (HWISI) was 24.6. Hurricane Orlene was capable of causing localized serious damage.

Hurricane Orlene will move through an environment unfavorable for intensification during the next 24 hours. Orlene will move over water where the Sea Surface Temperatures are near 29˚C. However, an upper level trough over northwestern Mexico will produce southwesterly winds that will blow toward the top of Orlene’s circulation. Those winds will cause the vertical wind shear to increase. Stronger vertical wind shear will cause Hurricane Orlene to continue to weaken during Monday.

Hurricane Orlene will move around the western end of a high pressure system over Mexico. The upper level trough over northwestern Mexico will steer Hurricane Orlene toward the north-northeast during Sunday night and Monday. Orlene will bring strong, gusty winds and locally heavy rain to Las Islas Marias. Locally heavy rain could cause flash floods in some locations. Hurricane Orlene could cause a storm surge of up to 10 feet (3 meters) in parts of Las Islas Marias. Orlene could cause serious damage in Las Islas Marias. On its anticipated track Hurricane Orlene is likely to make landfall on the west coast of Mexico between San Blas and Mazatlan on Monday afternoon. Orlene will bring strong gusty winds and locally heavy rain to the coast. Heavy rain could cause flash floods in parts of Nayarit and southern Sinaloa. Hurricane Orlene could produce storm surge of up to 7 feet (2 meters) along the coast.

Tropical Storm Nora Brings Rain to West Coast of Mexico

Tropical Storm Nora brought rain to the west coast of Mexico on Sunday. At 8:00 p.m. EDT on Sunday the center of Tropical Storm Nora was located at latitude 24.5°N and longitude 107.7°W which put it about 85 miles (135 km) east-southeast of Los Mochis, Mexico. Nora was moving toward the north-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 992 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Mazatlan to Topolobampo, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Topolobampo to Huatabampito, Mexico.

Tropical Storm Nora moved northward along the west coast of Mexico on Sunday. The center passed near Mazatlan and Culiacan. The center remained over land during its northward track and former Hurricane Nora weakened to a tropical storm. Tropical Storm Nora dropped heavy rain over parts of Nayarit, Sinaloa and Durango. The heavy rain may have caused flash floods in some location.

Tropical Storm Nora will continue to move toward the north-northwest near the west coast of Mexico during the next 48 hours. On its anticipated track the center of Nora will remain over land. So, Tropical Storm Nora will continue to weaken. Nora could bring locally heavy rain to Sinaloa, Sonora and Chihuahua as the tropical storm weakens over northwestern Mexico. The risk of flash floods will be high in those location.s

Tropical Storm Dolores Drops Heavy Rain over Western Mexico

Tropical Storm Dolores dropped heavy rain over western Mexico on Saturday. Dolores weakened to a tropical depression on Saturday evening when the center moved inland. At 8:00 p.m. EDT on Saturday the center of Tropical Depression Dolores was located at latitude 21.3°N and longitude 104.2°W which put it about 80 miles (130 km) northeast of Puerto Vallarta, Mexico. Dolores was moving toward the north-northwest at 20 m.p.h. (32 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 1001 mb.

Tropical Storm Dolores made landfall on the coast of Mexico southeast of Manzanillo on Saturday afternoon. The maximum sustained wind speed was 70 m.p.h. (110 km/h) at the time of landfall. Dolores moved steadily toward the north-northwest after it made landfall. The lower part of the circulation around Tropical Storm Dolores weakened quickly when it moved inland over the mountains in west central Mexico. Even though it was weakening, rising motion in portions of the circulation around Dolores was enhanced in places where the air moved up the sides of mountains. Tropical Storm Dolores dropped heavy rain over parts of Michoacan, Colima, Jalisco and Nayarit.
