Around South Florida, some residents are cautiously preparing for Erika.
It’s not yet clear if Erika will be a full blown hurricane or a lesser storm that will impact South Florida.
Michael Amend of Miami Beach was stocking up on water at Home Depot in North Miami -- just in case.
"I think you have to take it seriously and wait and see how it develops," he said.
Angie Bryan who lives in Miami Shores, said she was making sure she had extra cannisters of propane. In case of a power outage, she plans to fire up her grill to cook.
Angie says propane is important after a storm if she loses power.

Government officials are encouraging people to prepare for the storm. Even if it isn’t a hurricane, Erika could bring heavy rains, flooding and possible power outages.
