A new tropical depression formed June 14, 2018, on the same day Tropical Storm "Bud," the second named storm of the 2018 East Pacific hurricane season, was making landfall along the southern tip of Baja California Sur. This new storm is currently a stationary system but is expected to slowly drift towards the coast and become a tropical storm, named Carlotta, before it makes landfall.
At 12:00 UTC on June 15, the center of Tropical Depression Four-E was located 170 km (105 miles) S of Acapulco, Mexico. Its maximum sustained winds were 55 km/h (35 mph) and minimum central pressure 1 007 hPa.
The depression is currently stationary, but a slow drift toward the northeast and then north is expected through the coming weekend and the center of this storm could reach the coast of southern Mexico by Sunday, June 17 as a tropical storm.
A Tropical Storm Warning is currently in effect for Tecpan de Galeana to Punta Maldonado. Tropical Storm Warning means that tropical storm conditions are expected within the watch area, generally within 36 hours.

The storm is expected to produce 76 to 152 mm (3 to 6 inches) of rain along the Guerrero coast, including the city of Acapulco, with isolated higher amounts approaching 203 mm (8 inches) possible.
These rains could produce life-threatening flash floods and mudslides.
Swells generated by the depression are affecting portions of the couas of southern Mexico and are likely to cause life-threatening surf and rip current conditions.
