Weather forecasts are calling for strong winds beginning overnight tonight and lasting into the overnight period tomorrow. After a brief reprieve, winds are expected to pick up again Tuesday afternoon with strong winds lasting into Thursday. Forecasts are calling for sustained winds out of the east of 30 km/hr overnight tonight rising to over 40 km/hr by noon tomorrow. During this period temperatures are expected to be just below freezing. Winds are then expected to switch to a southerly direction, peaking tomorrow evening at speeds of over 45 km/hr from the south or southwest with gusts of 70 km/hr. Waves are expected to reach 2m in height. Winds are then expected to diminish to a southwesterly direction of less then 30 km/hr during the overnight period. Tuesday afternoon, winds are expected to rise again over 30 km/hr from the southwest before switching to a more westerly direction, peaking in the evening at over 45 km/hr from the west with gusts of around 70 km/hr. Waves could be expected to reach 1.5 m in height. Strong westerly winds over 35 km/hr are expected to last into Wednesday morning before shifting to a northwest direction when they will then have little impact on the shoreline. During this overnight period temperatures are expect to be just below freezing. Weather forecasts, especially wind forecasts, this early can change substantially, but the various forecasters are generally in agreement.
Strong winds will be driving waves onto our Lake Erie shoreline in Chatham-Kent and Elgin County starting this evening and lasting through Wednesday morning. Throughout this entire period there is a risk that wave action could damage shoreline protection works and cause shoreline erosion. In flood prone areas, such as Erie Shore Drive, and some specific areas around Wheatley, there is a risk of flooding caused by waves crashing against the shoreline protection works and spraying water up onto the land. While temperatures are beneath freezing, overnight tonight and tomorrow morning, as well as the Tues/Wed overnight period, there is risk that this spray will freeze causing hazardous conditions. While winds are out of the east and southeast direction, overnight tonight and into Tuesday, there is an increased risk for the Rose Beach Line area in Chatham-Kent as recently strong winds from that direction have caused erosion in the area and caused sand to block the outlets of creeks and municipal drainage leading to backup flooding. As winds switch to a more southerly direction, tomorrow afternoon through Tuesday afternoon, the risk increases for the Erie Shore Drive area. Blocked drainage outlets can also cause issues in this area as well. Residents along the Lake Erie shoreline should pay attention to weather forecasts as they could change and prepare accordingly.
People should take extra caution and avoid the shoreline should conditions get rough. The waves can be strong and the shoreline slippery. There could also be hazardous debris within the waves and water which could be thrown onto the shoreline. Freezing spray can also create slippery hazardous conditions, especially if it makes it to the roadways. Standing water can also present unseen hazards. Children and pets should be kept away from the water. Officials will continue to monitor the situation and update this advisory if necessary.
