Tropical Storm Norma Nears Sinaloa

The center of Tropical Storm Norma neared the coast of Sinaloa on Sunday night. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Norma was located at latitude 25.0°N and longitude 109.0°W which put it about 55 miles (90 km) south of Los Mochis, Mexico. Norma was moving toward the east-northeast at 5 m.p.h. (8 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 990 mb.

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

Tropical Storm Norma weakened on Sunday night as it neared the coast of Sinaloa. The center of Norma’s circulation was still over the warm water in the southern part of the Gulf of California. However, an upper level trough west of Baja California produced strong southwesterly winds that blew the upper part of Norma’s circulation northeast of the circulation in the lower levels. The lower part of Tropical Storm Norma consisted primarily of bands of showers and lower clouds. Winds to tropical storm force extended out 150 miles (240 km) in the eastern part of Norma’s circulation. Winds to tropical storm force extended out 90 miles (145 km) in the western part of Tropical Storm Norma.

Tropical Storm Norma will make landfall on the coast of Mexico south of Topolobampo on Monday. The lower part of Norma’s circulation will weaken rapidly after it makes landfall. Isolated heavy rain could fall in Sinaloa where the wind pushes air up slopes. Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Otis formed south of Mexico. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Otis was located at latitude 11.1°N and longitude 97.3°W which put it about 435 miles (705 km) south-southeast of Acapulco, Mexico. Otis was moving toward the north-northwest at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1004 mb. Tropical Storm Otis could move toward Mexico during the next few days.

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
