Tropical Depression Dolores Discussion Number 8
NWS National Hurricane Center Miami FL EP042021
1000 PM CDT Sat Jun 19 2021
Satellite imagery and surface observations indicate that Tropical
Depression Dolores continues to rapidly weaken. It is getting very
difficult to locate a low-level center at this time, if one still
exists over the mountainous terrain. Given the length of time
already spent over this terrain, the estimated initial intensity is
being lowered to 25 kt for this advisory.
Dolores is moving north at 18 kt between a ridge to its east and a
mid-level low to its west. This motion is expected to continue
through tonight, keeping Dolores well inland over western Mexico.
This track over the rugged terrain should cause Dolores to finally
dissipate late tonight or on Sunday morning.
Although Dolores may dissipate soon, the abundant moisture
associated with the system is expected to continue to produce heavy
rainfall over portions of southwestern and west-central Mexico for
the remainder of the weekend.
1. Wind gusts to near tropical storm force will likely continue over
coastal sections of west-central Mexico to the south of Puerto
Vallarta through early tonight.
2. Heavy rains are forecast over coastal sections of the Mexican
states of Guerrero, Michoacan, Colima, Jalisco, Nayarit, and
southern Sinaloa through Sunday, which could result in
life-threatening flash flooding and mudslides.
