Ponce, Puerto Rico (CNN)Tropical Storm Dorian is set to slam Puerto Rico’s eastern half Wednesday afternoon with heavy rains — and potentially flooding and landslides — along a similar path and with impacts to many of the areas hardest hit two years ago by Hurricane Maria.
Dorian’s wind speeds won’t approach those of the Category 4 storm that left 2,975 people dead in 2017. But they’ll be enough to strain Puerto Rico’s fragile power infrastructure, CNN meteorologist Chad Myers says, and spread misery across a territory where blue tarps still cover some of the holes that Maria ripped in homes’ roofs.FOLLOW LIVE UPDATESDorian could dump as many as 10 inches of rain in parts of Puerto Rico and the British and US Virgin Islands, the National Hurricane Center says.”That means flooding, and you can get some landslides, too. So, we’ve just really got to pay attention,” Ken Graham, the center’s director, told CNN’s “New Day” on Wednesday.Read MoreDorian’s center was in the Caribbean Sea on Wednesday morning, southeast of the US Virgin Islands, with maximum sustained winds of 60 mph. Its outer bands were dropping rain on St. Croix.TRACK THE STORMIts projected path has shifted significantly over the past day. Dorian once was projected to swing south of Puerto Rico and rumble over the Dominican Republic. The forecast now anticipates the center missing Hispaniola altogether, though the Dominican Republic still could get tropical-storm rain and winds.After it passes Puerto Rico, Dorian will strengthen over warm Atlantic waters and is expected to approach Florida or other parts of the US Southeast coast over the Labor Day weekend as a hurricane. It’s still far too early to know exactly where or when the storm could hit the US mainland.Men board up a shop’s windows ahead of the arrival of Tropical Storm Dorian in Boqueron, Puerto Rico.Puerto Rico bracing for impact”There’s already so much damage on the ground from (Maria) that this isn’t going to take a lot to make a significant amount of damage, especially flooding,” Myers said.In the city of Ponce on Puerto Rico’s southern coast, people still have tarps over their homes, Mayor Maria “Mayita” Melendez told CNN. The city was hit with $1 billion in damages from Maria, she estimates.One resident, Lucy Beascochea, said the tin roof over her home still has holes in it, meaning every time it rains, water leaks in. She is nervous about the approaching storm, she told CNN. Puerto Rico Gov. Wanda Vázquez Garced on Monday declared a state of emergency for the island and urged people to prepare for the storm.”For citizens who do not yet have safe roofs, we will have shelters ready,” Vázquez said on Twitter.Schools across Puerto Rico are closed Wednesday.About 360 shelters are available across the island for a capacity of 48,500 people, the government’s official Twitter account said Monday. And about 70 hospitals were prepared to handle emergencies, officials said.”Thankfully, I’ve been preparing since May,” said Krystle Rivera, whose family has been stocking up on water, canned food and gas in anticipation of the hurricane season.
