Heavy Rain in Florida Brings Floods to Miami

“Turn around, don’t drown,” she said.

Officials in Miami, Fort Lauderdale and other cities were distributing free sandbags on Friday. Miami’s zoo said on Friday that it would be closed through Saturday to allow staff members to prepare the facility for the storm. In Key West, an L.G.B.T.Q. street festival to kick off Pride Month was canceled.

In Palmetto Bay, an incorporated suburb about 15 miles south of Miami, officials were particularly concerned on Friday about the possibility of heavy rains, given that almost all of the village’s eight square miles were in a flood zone.

“We’re encouraging residents to keep their storm drains clear of debris,” Mayor Karyn Cunningham said. She noted that the village had increased its yearly budget for drain clearing but urged its 25,000 residents to play their part, including by keeping roads clear of obstructions and drains free of landscape clippings.

“We’ve been preparing for months for the upcoming hurricane season and take emergency response seriously,” Ms. Cunningham said. “We have to focus people’s minds around the fact that it’s hurricane season.”

Caroline Horn, the manager of a group that fights against flood insurance price hikes in the Florida Keys, said the warnings began early.

“I’m already getting notices on my phone to watch out for standing water,” Ms. Horn said. “We check the radar, every day, multiple times a day.”

Hurricane Agatha, the first named storm in the eastern Pacific region, roared into Mexico this week as a Category 2 storm with heavy rains and damaging winds. It killed at least nine people and left five others missing, the governor of the southern state of Oaxaca, Alejandro Murat, said on Friday morning.
