Mexico faces dual storm threat: Barry’s remnants move inland, Flossie poised to become hurricane

The National Hurricane Center (NHC) said that what was once Tropical Storm Barry will continue to bring heavy rain to portions of eastern Mexico over the next few days after the system made landfall late Sunday night.

Barry was downgraded to a tropical depression after the system made landfall and dissipated by early Monday morning, but heavy rain is likely to continue over the next few days, the NHC said.

In addition to Barry, Tropical Storm Flossie formed in the Eastern Pacific Ocean off the southwestern coast of Mexico late Sunday morning, and the system is expected to strengthen into a hurricane early this week.

The NHC said that Flossie will continue to see steady to rapid strengthening over the next few days, and the system will likely become a hurricane on Monday night or Tuesday morning.
