Tropical storm Carlotta has formed in the Eastern Pacific and is expected to strengthen into a hurricane within 36 hours. The storm poses a threat for southern Mexico, specifically around the Gulf of Tehuantepec. This is to the east of Acapulco. Carlotta will make landfall at 70 knots (a category I hurricane), weaken overland and reemerge over water near Acapulco, then hang around near there as a tropical storm.
