Tropical Storm Kristy: Life-threatening surf for Mexico's Pacific coast

Tropical Storm Kristy was expected to create life-threatening surf and rip currents of the coast of southern Baja California and southwest Mexico over the next few days, the National Hurricane Center warned Friday.

The NHC said winds had weakened to 50 mph by Friday afternoon but still posed a danger.

Tropical storm-force winds extended about 140 miles from the center.

“Swells generated by Kristy will affect portions of the coast of southwestern Mexico and southern Baja California during the next day or two,” the NHC notice said.

“These swells are likely to cause life-threatening surf and rip current conditions,” it added.

Meanwhile in the Atlantic, Tropical Storm Nadine had maximum sustained winds of 70 mph and was about 765 miles east-southeast of Bermuda, according to the NHC.

It was expected to turn north Friday and then head northeast toward the Azores Islands.

The NHC said little change in Nadine’s strength was expected but added “any strengthening would allow Nadine to become a hurricane.”

Storm-force winds extended about 230 miles from the center.
