The combination of king tides and heavy rain poses a significant flooding risk to low-lying and coastal areas in South Florida, particularly in Miami-Dade, Broward, and the Florida Keys. Moderate saltwater flooding is possible within 1.5 to 2 hours of high tide. Additionally, localized flooding from heavy downpours may disrupt travel and create hazardous conditions on roads. Smoke from the Alpha Sierra Fire in western Broward, which has burned 330 acres and is 16% contained, could also affect air quality in parts of Broward and northern Miami-Dade counties, though shifting winds are expected to push the smoke inland later in the day.
