A low pressure system over the Eastern North Pacific Ocean near Zijuatanejo strengthened on Friday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Mario.

The circulation around Tropical Storm Mario exhibited more organization on Friday morning.  More thunderstorms developed near the center of Mario’s circulation.  Thunderstorms were also occurring in short bands that were revolving around the center of Tropical Storm Mario.  Storms near the center of Mario generated upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Mario was very small.  Winds to tropical storm force extended out 25 miles (40 km) in the northwestern quadrant of Mario’s circulation.  The winds in the other parts of Tropical Storm Mario were blowing at less than tropical storm force.

Tropical Storm Mario will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Mario will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of upper level ridge over Mexico.  The upper level ridge will produce northeasterly winds that will blow toward the top of Mario’s circulation.  Those winds will cause moderate vertical wind shear.  The circulation around Tropical Storm Mario could also pull drier air over Mexico in the tropical storm.  The moderate vertical wind shear and drier air will inhibit intensification.  Tropical Storm Mario could intensify during the next 24 hours if the center remains over the ocean.

Tropical Storm Mario will move around the around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer Mario toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Mario will move near the coast of Michoacan.

Tropical Storm Mario will bring gusty winds and locally heavy rain to coastal parts of Michoacan.  Heavy rain could cause flash floods in some locations.
