Sunday August 26, 2018 Tropical Depression 15E has evolved into Tropical Storm Miriam some 1210 miles to the southwest of Cabo San Lucas. Miriam is forecast to strengthen over the next 24hrs and become a hurricane as it moves to the west-northwest. Tropical Cyclone Miriam should pose no threat to the Baja peninsula as it has formed in a position that will take it into the Central Pacific in the next 48hrs, before the system turns more to the north.
At 9Am Tropical Storm Mioriam was located near 13.2N 125.3W and was moving 275° at 11kts. Central barometric pressure was 1004Mb and winds were 40-50 kts making Miriam a Tropical Storm. Tropical Storm force winds extend out 30 miles in all but the southwest quadrant.
Miriam is forecast to achieve Hurricane intensity sometime late Monday as it moves west into the Central Pacific. The system should pose no threat to the Baja peninsula.
There will be no further updates to this page unless Miriam’s threat to the Baja peninsula should change.
