Though protesters vow to stay put, if the weather threatens their safety or that of visitors on the streets, police officers will use public address systems and go person-to-person to warn them to leave, said Tampa Police Chief Jane Castor.
Castor said if "it becomes an issue of public safety, we will order people into shelters."
At least one arrest was made. A man that police said had a machete strapped to his leg was subdued after he resisted officers, according to the Hillsborough County Sheriff's Office.
