Tropical Storm Bertha may brush Atlantic Canada

Projected path of Bertha this week. (The Weather Network)
Tropical storm Bertha is located about 220 miles (350km) east of Great Abaco Island in the Bahamas this morning. Bertha, the second Atlantic storm of this young season, has 70mph (110km) winds and is moving north at 16mph (26km) and is expected to remain well off the U.S. east coast as it becomes a hurricane later today. The storm will begin to weaken on Tuesday as it approaches the coastal waters of Atlantic Canada. At this time is is not clear just how close to the coastal area of Nova Scotia that Bertha will pass. Computer models are generating very different scenarios, but a direct hit is not expected. Rough surf/seas and heavy rains main be the main impacts to Nova Scotia and later in the week Newfoundland. Offshore waters will have storm conditions with high surf and strong winds. Warnings or a watch may be required for a portion of the region later today.

The weather in Montreal over the weekend was warm and very humid, a little smokey on Saturday, with lots of thunderstorms around. The main area of storminess remained along the US/Ontario/Quebec border southwest of Montreal. Some flooding was observed in the Adirondacks of New York as storms trained over the same area both days. A few showers moved into the metro area overnight, but that should be all for today. Temperatures will be warm again today reaching 28C (83F) in Montreal. I managed two 30C (86F) days in a row at my home on L'Ile Perrot for both Saturday and Sunday. Lows tonight will be mild around 20C (68F).

The sunshine today will eventually give way to increasing clouds by Tuesday morning as a cold front moves into the St. Lawrence Valley. Look for showers and thunderstorms to develop by mid-day Tuesday. It will be cooler with a high of 23C (73F). The balance of the week looks fair, cool at first, but with a warming trend into next weekend.
