HONOLULU — Tropical Storm Lala formed Thursday in the Pacific Ocean and a hurricane watch has been issued for the Big Island of Hawaii, where it could bring heavy rain and flooding this weekend, forecasters said.
The storm is forecast to bring rain to the Hawaiian Islands starting late Friday as well as high winds and dangerous surf, the National Hurricane Center said.
Lala was about 700 miles (1,127 kilometers) east-southeast of Hawaii with maximum sustained winds of 40 mph (64 kph), the Miami-based center said. It’s moving west.
Strengthening is forecast, and Lala could be near hurricane strength as it approaches the Big Island. A hurricane watch means that hurricane conditions are possible, and it is typically issued 48 hours ahead of potential tropical-storm-force winds.
The system could bring rainfall totals of 5 to 10 inches (13 to 25 centimeters) in the island chain, with up to 20 inches (51 centimeters) possible, forecasters said. That could produce flooding and mudslides, the center said.
Also in the Pacific, Tropical Storm Hernan formed Thursday but that storm wasn’t threatening land.
Hernan was about 1,460 miles (2,350 kilometers) west of the southern tip of the Baja California peninsula of Mexico, the center said. Maximum sustained winds were around 45 mph (72 kph) and it was moving west-southwest.
In the Atlantic Ocean, former Tropical Storm Cristobal weakened and degenerated into a post-tropical remnant low on Thursday, the center said. It was about 500 miles (805 kilometers) west of the Azores and didn’t threaten land.
