East Coast - Cape St. Francis and south: Warnings

Warnings (In effect)

High water level warning in effect

East Coast

Issued 09:30 AM NDT 29 August 2014 With the passage of hurricane Cristobal well offshore of Newfoundland, its rapid forward speed of travel over the Southern Grand Banks may trigger rapid tide-like changes in harbour water levels over Eastern Newfoundland. The most probable period for this would be later this morning and into the afternoon and areas most prone to this range from the Southern Avalon to the Bonavista Peninsula. Tropical storms that have raced across the Grand Banks (moving over 100 km/h) in the past have caused water levels in harbours to rise and fall 2 or 3 times over the span of an hour and fluctuate by as much as 2 or 3 metres (6 to 10 feet). This is an advisory that this may - repeat may - occur and interests along the coast should be on the watch for this possibility. Predicting the actual water level changes for various harbours is very difficult. The high (natural) tide in the region will be in the 10:30 to 11:30 AM time frame and will be low in the 4:30 to 5:30 PM time frame.

In effect from 10:00 A.M. to 2:00 P.M. today.

Mariners are advised to monitor this marine warning for the most current information.
