Mario was moving toward the west-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).

After almost dissipating during Friday night, Tropical Storm Mario re-developed south of Baja California on Sunday morning. A distinct low level center of circulation re-formed on Sunday morning. More thunderstorms started to develop near the low level center of circulation. Bands of showers and thunderstorms were revolving around the center of Tropical Storm Mario. Storms near the center of Mario began to generate upper level divergence that pumped mass away from the tropical storm.
The circulation around Tropical Storm Mario was still small. Wind to tropical storm force extended out 25 miles (40 km) in the northeastern 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 28°C. It will move under the southeastern part of upper level ridge over the southwest U.S. and northwest 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 moderate vertical wind shear will inhibit intensification, but the wind shear will not be enough to prevent intensification. Tropical Storm Mario is likely to intensify during the next 24 hours.
Tropical Storm Mario will move around the around the southern part of a high pressure system over the southwest U.S. and northwest 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 southwest of Baja California.
