[ARCHIVED] Get Ready for King Tides

King-Tides-

Unusually high tides, also known as King Tides, are expected periodically through early December. Flooding in low-lying areas is more likely during this time of the year due to the close proximity of the moon which creates King Tides. These seasonal high tides, combined with rising sea levels and inclement weather conditions, exacerbate flooding risks. Rainfall and wind strength and direction also have a significant impact on the height of the tides causing them to come in higher or lower than predicted. With seven miles of shoreline, hundreds of miles of canals, and a flat topography, Hollywood is vulnerable to the effects of sea level rise and tidal flooding.

Based on the National Oceanic and Atmospheric Administration’s tide predictions, above average high tides are expected:

  • September 9-11
  • October 5-11
  • October 20-21
  • November 3-9           
  • December 2-7

Above average high tides are also expected again, on both the new moon and the full moon, additional dates to watch for tidal impacts include: 

  • September 18-22
  • November 18-19

High seasonal tides can cause low-lying coastal areas to flood. Motorists are urged to use caution and seek alternate routes to avoid traveling on flooded streets. Coastal roads, parking lots and docks in vulnerable areas could flood during the times of high tide.  

Seasonal tides could raise the water level by more than 2 and a half feet during high tide. The City is working on both short and long-term solutions to minimize the impacts of tidal flooding and has completed the installation of flap gates in the stormwater system to help prevent tidal water from flowing back through the stormwater drains. Additionally, auxiliary pumps are stationed in high risk areas to help clear flooded streets as quickly as possible.
