Currently in Toronto — August 24th, 2022

Sunny periods and humid

The weather, currently.

A pretty good midweek day on the way. As a low pressure system moves out -  a ridge of high pressure will move in. Wednesday morning will start under mainly sunny skies and a wake-up temperature near 17 °C. There will be some clouds by late morning with a overall mix of sun and cloud. There is a risk of a few spotty showers for the afternoon. A lake breeze may be just enough help squeeze out some moisture in some areas. The high will be 28°C, feeling like 34°C with the humidex. The wind be light from the west and the UV Index will be 8 or very high.

Wednesday night: a few scattered clouds and a low of 18°C.

What you need to know, currently.

The 2022 Atlantic season is off to its slowest start in 30 years.

Two recent Gulf tropical disturbances failed to become depressions or storms, but activity is expected to rise in the next few weeks. Right now, that leaves us with three named storms: Alex, Bonnie and Collin. Colorado State University tropical scientist Phil Klotzbach stated that this was the first time in 40 years that no named storms formed between July 3rd and August 22nd in the Atlantic Basin.

So why is this happening? First, there is Saharan dust present in the main development region of the tropics.

“The persistent dust is a problem because it smothers any developing thunderstorms in the Atlantic that have any potential of becoming a tropical storm,” said Megan Montero, Currently’s Interim Chief Meteorologist.

In short, the strong low latitude wind in combination with sinking air hinders storm formation. There are also high winds across the Atlantic basin. And, the high pressure system that’s usually found over Bermuda at this time is farther north, resulting in heat waves and intense droughts that cause even more dry air.

While there’s no known correlation between a slower hurricane season start and intensity nor how the rest of it goes down, Klotzbach points out that 90 percent of all Category 3 or stronger Atlantic Basin hurricanes happened after August 20th. Also, the peak of the season usually occurs around September 10th.

“Do not count the season out yet,” said Montero. “There are still several atmospheric and oceanic conditions that favor an active hurricane season.”

For example, we’re in a La Nina year, which tend to see more Atlantic hurricane activity. There are also weaker tropical Atlantic trade winds, an active African Monsoon and higher sea surface temperatures.

In the meantime, it’s important to stay prepared!
