Tropical Depression Two-E has strengthened into Tropical Storm Boris off Mexico's southern Pacific coast, located approximately 95 miles south of Acapulco with maximum sustained winds of 35 mph. A tropical storm warning remains in effect for the southern Mexican coast from Laguna de Chacahua to Tecpan de Galeana, with the system expected to make landfall early Monday. Forecast rainfall of 3–10 inches (up to 12 inches) across Guerrero and Oaxaca poses flooding and mudslide risks, including for the Acapulco resort area.

Impact verdict

Low impact. LOW: A weak tropical system (35–45 mph forecast at landfall) affecting a relatively limited stretch of the southern Mexican Pacific coast. Acapulco is a significant resort and commercial centre, so heavy rainfall-driven flooding and infrastructure disruption are plausible, but the storm is not forecast to reach hurricane intensity and no insured loss estimates have been reported. Watch-list event for catastrophe and reinsurance monitoring; unlikely to produce market-moving losses at forecast intensity, though localized urban flooding near Acapulco could generate some property and business interruption exposure.
