A new moon combined with easterly winds could cause flooding in some low lying areas beginning Sunday, according to the National Weather Service.
The worst case scenario could mean that tides rise about a foot more than their normal levels, said meteorologist Stephen Konarik.
“Normally the affects of the moon is not enough to cause coastal flooding,” he said. “But when you have meteorological factors, you never know.”
A cold front moving through Saturday will bring winds from the east, and when that’s added to the effects of the new moon, it could cause problems in flood-prone areas, including South Beach.
The National Oceanic and Atmospheric Administration (NOAA) predicts that the South Florida region will once again have unusually high tides this fall.
Last year, areas of Miami Beach and parts of A1A in Fort Lauderdale experienced extremely high tides, sending water cascading into the streets.
Based on the gravitational pull of the moon, NOAA believes the highest tides will be Nov. 3rd through 6th, Nov. 15 and Dec. 3 through 6th.
Miami-Dade officials sent out a news release Friday warning residents to avoid standing water.
According to the county, the extreme tides highlights the need to plan for the impact of coastal flooding.
The topic will be discussed at the fifth annual Southeast Florida Regional Climate Summit Nov. 7-8 at the Broward Convention Center in Fort Lauderdale.
