Miami-Dade's midnight curfew could be tweaked. Mayor Daniella Levine Cava is expected to announce whether or not she's lifting the midnight-to-6am curfew that has been in effect since July. Commissioner Keon Hardemon says it's time. Levine Cava says she can only lift the curfew if the 14-day positivity rate is below 5.5-percent. She has been meeting with medical advisors to discuss hospitalization rates, deaths and percent of vaccinated residents ahead of her announcement.
