Lidia is currently about 45 miles west of La Paz, Mexico and given the interaction with land, weakening is expected over the next couple of days.
A tropical storm warning has been issued for the Baja California Peninsula from San Jose de Las Palomas to Isla San Luis and also for mainland Mexico from Altata to Puerto Libertad. A tropical storm warning indicates tropical storm conditions are expected within 36 hours.
A track to the northwest is expected to continue into this weekend, essentially taking the center of Lidia up along or near the west coast of the Baja California Peninsula.
Gusty winds and heavy rain will affect Los Cabos through Friday. Impacts in the rest of the southern Baja will continue into Saturday. Keep in mind that wind speeds atop and on the windward sides of hills and mountains are often up to 30-percent stronger than the near-surface winds.
Rainfall accumulations of 6 to 12 inches are expected across the Mexican states of Baja California Sur into Baja California, Sinaloa and coastal areas of Sonora, with locally higher amounts up to 20 inches possible.
This heavy rainfall may result in life-threatening flash flooding and mudslides.
Flooding impacted San Jose del Cabo on Thursday, with almost 12 inches of rainfall reported.

Along the eastern coast of Los Cabos there were additional flood concerns with reports that East Cape arroyos were already in flood stage, according to Pete Thomas Outdoors.
In addition, a dangerous storm surge is expected to produce significant coastal flooding near and east of the center of this system over the southern portion of Baja California Sur.
High surf and dangerous rip currents are also anticipated.
There is a chance some of the tropical moisture associated with Lidia could enhance thunderstorm activity in parts of the Desert Southwest this weekend.
By late this weekend, Lidia will begin to weaken and become a remnant low as it interacts with land and cooler water temperatures west of the Baja California Peninsula.
