Hurricane Raymond is gaining power as it swirls toward Mexico’s already soaked southern Pacific coast, bringing the threat of heavy and possibly dangerous rains a month after Tropical Storm Manuel caused widespread damage with floods and mudslides.

The U.S. National Hurricane Center said late Sunday that the newly formed storm was likely to veer back out into the Pacific before reaching land, but forecasters warned that Raymond still might pass close to shore and deliver heavy rains to the drenched region.
