Rising humidity in Newfoundland

Tuesday, July 29, 2014, 12:17 PM - Much of Newfoundland is sweltering beneath intense humidity, and there's no relief until after Wednesday.

"A warm humid air mass will move over Newfoundland today and raise temperature and humidity values," Environment Canada says in a special weather statement issued for most of the island, including St. John's. 

The agency advises avoiding outdoor strenuous activity or, if you can't, drink plenty of fluids, especially water, and reschedule outdoor activities to cooler parts of the day.

That kind of intense humidity is good thunderstorm fuel, and non-severe storms are possible this afternoon in eastern Newfoundland, including parts of the Avalon peninsula.

Newfoundland has been experiencing above seasonal summer temperatures, and St. John's in particular is having its warmest July on record, with more days above the 25^oC mark than Toronto so far this season.

The Maritimes is not in any humidex advisories, but it's also been having a warm streak, and Charlottetown, PEI, in particular is expected to feel like 30 with the humidity Tuesday.

However, today will mark the end of that streak. Although temperatures will be in the mid-20s, feeling hotter with the humidity, they will begin a slow return to seasonal norms.

Non-severe thunderstorms are expected Tuesday afternoon in northern New Brunswick and in Cape Breton Island.
