This month's new
moon is bringing exceptionally high-tide cycles and coastal flooding to South
Florida into Monday.
Portions of the Florida Keys and Barrier Islands east of Miami began to feel the effects of the incoming King Tide last Friday as saltwater erased area beaches and inundated low-lying roadways.On Saturday morning, the tide measured at
Virginia Key reached 2.94 feet above mean sea level, which is the second highest water level of the year, with Dorian's assisted storm surge of 2.95 feet on Sept. 3 remaining the highest, according to Brian McNoldy, a Senior Research Associate at the University of Miami's Rosenstiel School.Some locales across South Florida can continue to expect to have high-tide cycles some 3 feet above normal levels into Monday.These exceptionally high tides are caused by the gravitational force of both the sun and the moon on the oceans, acting to displace more ocean water into certain areas.The cities of Miami and Miami Beach are no stranger to this phenomenon and the issues that come along with it.More than a dozen temporary pumping stations have been put in place across Miami Beach alone in anticipation of the sunny day flooding.

Gardens should be flushed out with fresh water after the tides recede to avoid damage.The excessively high tides are expected to settle down after Monday as the moon heads towards the first quarter phase.Additional higher-than-normal tides are forecast near the Oct. 13 full moon and again during the next new moon around Oct. 27.
