Nova Scotia, along with the rest of the world, is seeing the highest tides in almost two decades peaking today.

The tides are the result of the full moon which is in a "particular position where it is closer to the Earth than normal," said Robin Tress, a marine ecologist and coastal advisor with the Ecology Action Centre.

"We're seeing tides up to 15 per cent higher than normal, which is bringing more water farther inland."

The most dramatic effect of the high tides will be seen along the Bay of Fundy where the water will rise about a metre and a half higher than usual, Tress said.

The high tide in Baxters Harbour, which is along the bay, is at 1:32 p.m. AT.

Coastal communities, especially where there are rivers and streams, may be vulnerable to flooding, she said. The effect will not be as great along the Atlantic coast of the mainland and Cape Breton.

Tress recommends people with waterfront properties and who live along coastal rivers and other waterways move lawn mowers, patio furniture and other belongings farther away from the shoreline.

The rainfall forecast, which is calling for up to 100 millimetres of rain over the next two days, will also increase the risk of flooding.

"Clean out your gutters and move the Picasso out of the basement," Tress advised.

"The high tides are giving us a look at what coastal communities will experience as climate change progresses."

As the moon wanes and moves farther away from the Earth, the high-than-normal tides will recede as well, she added.
