Two storms were moving through the Pacific on Thursday.

Hurricane Polo brought heavy rain to Mexico’s west coast, while Tropical Storm Nolo headed toward Hawaii.

Residents in Mexico stacked sandbags and left their homes.

On Hawaii’s Big Island and Maui, people prepared for possible severe flooding.

The U.S. National Hurricane Center said Polo’s heavy rain could cause life-threatening flooding and landslides in Mexico.

In the port city of Lazaro Cardenas, seawater entered homes on Thursday.

Wooden planks and furniture were left scattered in the streets.

Polo has moved between Category 4 and 5, both major-hurricane strength.

Its strongest winds were expected to stay offshore as the center passed near the coast.

Tropical Storm Nolo was gaining strength far off the southern tip of Hawaii’s Big Island.

Forecasters expected hurricane conditions to reach the state Friday night.

Rain could total more than 2 feet (60 centimeters) on islands still recovering from earlier storms.

Schools were closed for the rest of the week.

Maui could also face life-threatening floods and mudslides, the hurricane center said.

Mexican authorities opened shelters and cleared people from beaches.

They deployed 15,000 security personnel and suspended schools as a precaution.

They did not immediately say how many people had been evacuated.

Guerrero state was at particular risk of flooding and mudslides, the hurricane center said.

Local worry was shaped by past storms, including Hurricane Otis in 2023, which plunged Acapulco into turmoil for weeks.

“So many people said it wouldn’t happen and then it did,” said Gonzalo Ramírez, a bartender in the city.
