The Pacific Disaster Center’s (PDC Global) Friday, June 30, 2023, Tropical Cyclone Activity Report…for the Pacific Ocean, the Indian Ocean, and adjacent Seas
Current Tropical Cyclones:
Tropical Cyclone 01E (Adrian)…is located about 405 miles southwest of the southern tip of Baja, California
Tropical Cyclone 02E (Beatriz)…is located about 50 miles south-southeast of Manzanillo, Mexico
Northeast Pacific Ocean:
Tropical Cyclone Adrian
ADRIAN MOVING WEST-NORTHWESTWARD TOWARD CLARION ISLAND
According to the NHC advisory number 14…
Adrian is moving toward the west-northwest near 8 mph (13 km/h) and this general motion is expected to continue during the next couple of days, followed by a turn toward the west on Monday.
Maximum sustained winds have decreased to near 90 mph (150 km/h) with higher gusts. Additional weakening is forecast during the next couple of days, and Adrian is forecast to become post-tropical on Sunday.
Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 80 miles (130 km).
HAZARDS AFFECTING LAND
SURF: Swells generated by Adrian are affecting portions of the west-central coast of Mexico and the southern Baja California peninsula. These swells are likely to cause life-threatening surf and rip current conditions.
Tropical Cyclone 02E (Beatriz)
BEATRIZ VERY NEAR THE COAST OF SOUTHWESTERN MEXICO…HURRICANE CONDITIONS AND HEAVY RAIN EXPECTED TO CONTINUE INTO SATURDAY
According to the NHC advisory number 9…
Beatriz is moving toward the northwest near 13 mph (20 km/h) and this general motion with a gradual decrease in forward speed is expected through Saturday night. On the forecast track, the center of Beatriz is expected to move near or over portions of the coast of southwestern Mexico through early Saturday. Beatriz is then expected to turn west-northwestward and move away from the west-central coast of Mexico late Saturday into Sunday.
Maximum sustained winds remain near 85 mph (140 km/h) with higher gusts. Beatriz is expected to remain a hurricane into early Saturday if its center remains just offshore the coast of southwestern Mexico. Weakening is expected later Saturday through Monday once Beatriz begins to move away from west-central Mexico.
Hurricane-force winds extend outward up to 25 miles (35 km) from the center and tropical-storm-force winds extend outward up to 90 miles (150 km).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected within the hurricane warning area through early Saturday. Hurricane conditions are possible within the hurricane watch area on Saturday. Tropical storm conditions are expected within the tropical storm warning area on Saturday, and are possible within the tropical storm watch areas Saturday or Saturday night.
RAINFALL: Through Monday, storm total rainfall of 3 to 5 inches, with maximum amounts of 8 inches, is expected across portions of southern and western Mexico from Michoacan northwest to Sinaloa and Durango in association with Hurricane Beatriz. This rainfall could lead to localized flash flooding and mudslides.
STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves.
SURF: Swells generated by Beatriz are forecast to spread northward along the southwestern coast of Mexico during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions.
