Photo contest asks to 'catch a king' tide
PORTSMOUTH (AP) — It's nearly time for above-average tidal ranges to show up on New Hampshire's coast, and one group is holding a photo contest to "catch a king" tide.
The New Hampshire Coastal Adaptation Workgroup says king tides happen naturally once or twice a year when the sun, moon and Earth align to produce the high tidal ranges. King tides bring in unusually high water levels and can cause local tidal flooding.
This year's tide is expected to reach 11 to 12 feet along New Hampshire's tidal shorelines from Monday through Wednesday during the lunch hour. A typical high tide for the region is between 8 and 10 feet.
Organizers say photos collected will be used to help residents, planners, and local officials identify coastal areas vulnerable to tidal flooding.
