US weather forecast

Florida is in the path of a potential tropical storm for the first time this hurricane season.

Residents could see heavy rain and strong winds from the system by the end of the week and into next week, according to the Florida Division of Emergency Management. It's still too early to determine where the storm might hit.

Gov. Ron DeSantis said Wednesday that residents could feel the effects of the storm into early next week. He encouraged everyone to prepare now by having at least seven days of disaster supplies.

The weather system, which should soon be Tropical Storm Isaias, was dumping heavy rain across the Leeward Islands of the eastern Caribbean on Wednesday, potentially unleashing "life-threatening" flash flooding and mudslides. This includes Puerto Rico and the U.S. and British Virgin Islands, reported USA Today.

After moving near Puerto Rico on Wednesday night, the system will affect the Dominican Republic and Cuba before making its way to the U.S. mainland, possibly Florida, by the weekend.

The National Hurricane Center said the system, dubbed Potential Tropical Cyclone Nine, is expected to strengthen before it makes landfall in the Dominican Republic on Thursday, although the center cautioned it’s still unclear what the storm would do in upcoming days.

“The details of the long-range track and intensity forecasts remain more uncertain than usual since the system does not have a well-defined center and it is expected to move near or over portions of the Greater Antilles later this week and move near or over Florida this weekend,” the center said.

"While this system could bring some rainfall and wind impacts to portions of Cuba, the central and northwest Bahamas, and Florida later this week and this weekend, it is too soon to determine the location or magnitude of those impacts," the center added.

Tropical storm warnings were issued for Puerto Rico and the U.S. Virgin Islands.

Officials in Puerto Rico expressed concern about the potential for landslides and flooding and noted the U.S. territory is struggling with a spike in coronavirus cases while also still recovering from 2017’s devastating Hurricane Maria and a string of earthquakes earlier this year that damaged or destroyed hundreds of homes in the island’s south.

The governor said that more than 300 shelters across the island were prepared to receive people if needed and that more than 130,000 face masks were available.

If Isaias forms, it would be another record-breaker for a season that hasn’t even reached the typical peak of hurricane activity. The current record for the earliest “I”-named storm is Irene on Aug. 7, 2005.

It is reported by Accu Weather that winds on some of the islands will get strong enough to cause property damage, knock over trees, and lead to power outages.

"Some intensification is expected over the next couple of days with damaging wind gusts of 40-60 mph in the Windward Islands and 60-70 mph with an AccuWeather Local StormMax™ of 80 mph possible over Hispaniola," AccuWeather Senior Meteorologist Rob Miller stated.

“Rainfall amounts of 2-4 inches can be expected with 4-8 inches and an AccuWeather Local StormMax™ of 10 inches possible over any higher terrain," Miller added.

Interaction with the islands in the northern Caribbean, especially the mountainous terrain of the larger islands, is expected to exert a drag on the feature and could take the edge off the overall strength. Such a close track over the islands of the northern Caribbean would also raise the risk to lives and property from flooding rain, mudslides, and strong winds.

The high mountains on Hispaniola, and to some extent Puerto Rico and Cuba, act as a natural barrier to the path of the storm. Tropical systems generally avoid tracking over the heart of these islands as a result. However, the mountains can cause the center of an approaching tropical storm or hurricane to jump from one coast to the other and re-form in the process.

The overall strength of the system may also determine its fate as far as a track is concerned. Early on, a well-organized, stronger system is more likely to curve northwestward and northward faster than one which remains poorly organized and stays weak.

Canada weather forecast

This entire week is expected to hover around the 30°C mark in Calgary, and Environment Canada has continued that trend by renewing its official heat warning for the Calgary region for the third day in a row.

The warning was first issued on Monday morning, which was then echoed by the government agency on both Tuesday and Wednesday mornings, stating that temperatures are expected to reach 29°C or higher, reported Canadian environment.

Wednesday’s warning does predict an end to the heat, stating that “temperatures are forecast to be a few degrees cooler for most regions on Thursday.”

Calgarians should also be looking out for heatstroke in themselves and those around them, with symptoms including lack of sweat, confusion, fainting, high body temperatures, and unconsciousness.

The Thompson-Okanagan remains under a heat warning as temperatures continue to climb and Environment Canada is reminding everyone to stay safe.

"It is hot and we're expecting over the next couple of days to get into the high 30s, perhaps touching 40 in some locations like Osoyoos," says Environment Canada Meteorologist Doug Lundquist.

Yesterday, Osoyoos was the hot spot for not only B.C. but all of Canada, reaching a high of 37.9 C.

"Around [July] 31 to the first of August is the hottest two days of the year. This is the hottest week of the year usually on average," says Lundquist.

The Thompson Okanagan has not yet hit any record highs this week, but Lundquist says some areas could break records over the next two days.
