Newfoundlanders reminded to keep hydrated amid record humidex

Thursday, July 31, 2014, 10:41 AM -

Wednesday marked a milestone for St. John's, with the city breaking an all time humidex record set back in 1967. The city basked in a humidex high of 38.7 Wednesday, beating the 38.5 record set back 47 years ago. 

As for Thursday, it doesn't look as though things will change much in terms of heat and humidity for southern parts of the island.

"Humidex values are forecast to approach record levels for St. John's again today," says Weather Network meteorologist Brett Soderholm. "In addition, much of the island will be feeling some humidity, although not as intense."

Environment Canada advises avoiding outdoor strenuous activity and drinking plenty of fluids, especially water.

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

Additionally, a southwesterly flow of humid air will continue to produce persistent fog today through Friday for the entire south coast of Newfoundland. 

"Fog will be most extensive during the night and morning hours, partially retreating to the coat during the day," says EC in a fog advisory. 

Fog is expected to dissipate in Port aux Basques and vicinity Friday morning.
