The weather, currently.

A frosty night ahead!

There's a frosty night ahead. Cold air is pushing in, making for a chilly Wednesday. There's a frost advisory in place for the city, but expect some sunny breaks early morning on Wednesday with a wakeup wind-chill near -5°C.

Gloves and a toque would be a good idea as the kids head off to school, as it will be a cold blustery day.  The high is just 5°C, (that's 10 degrees cooler than the norm). While we will see a few sunny breaks, cloud cover will dominate with a risk of an isolated flurry. There will also be some moderate wind gusts too from the NW at 20-40km/h.

Wednesday night will be mainly clear, but cold with a low of -2°C.

What you need to know, currently.

Today's climate modeling can help predict ocean heat waves, months in advance, according to new research from National Oceanic and Atmospheric Administration (NOAA) scientists.

Scientists say that the only sure way to prevent future damaging ocean heat waves is to reduce our reliance on fossil fuels. However, this modeling can help communities and scientists take preventative measures to protect ocean wildlife and reduce the stress placed on ecosystems.

“Today’s seasonal climate models could help to identify moments when taking extra care to reduce other threats could avert a devastating blow from which a fishery, a reef, or a whale population might not recover,” wrote NOAA.

Marine and ocean heat waves can be extremely disruptive to ecosystems. Coral reefs have been one of the most prominent cases of ecosystems affected by heat waves in recent years. According to NOAA, between 2014 and 2017, about 75 percent of global reefs experienced heat stress that triggered bleaching.
