People visiting the U.S, Mexico, Canada, and some regions of Central America should be prepared for travel disruptions due to some extreme weather condition this week. Weather extremes like Desert Southwest heatwaves and thunderstorms and monsoonal flooding in the Midwest and West will likely disrupt travel plans. Cities like Phoenix, Los Angeles, Dallas, Denver, and even parts of Ontario and Baja California are on high alert as forecasted. Let’s go over everything you need to know to travel this upcoming week.

Monsoonal Flooding: A Major Concern for US and Canada Tourists

The National Weather Service has warned of a ‘monsoonal flow’ that could bring intense thunderstorms and flash flooding from Nevada to Texas and Oklahoma. Forecasts predict heavy rainfall and strong thunderstorms, particularly across eastern Colorado, Texas, and Oklahoma. These conditions are likely to cause dangerous travel disruptions for visitors planning to explore key cities like Phoenix, Dallas, or Denver. For tourists planning outdoor activities or road trips, the storms may cause sudden closures on highways and other tourist routes.

Travellers heading to the Desert Southwest, including California and Nevada, should prepare for sudden changes in weather. While thunderstorms may bring much-needed relief from the oppressive heat, the heavy rain could create hazardous driving conditions, particularly in rural areas. Authorities recommend that travellers monitor local weather reports closely, especially in areas prone to flash flooding.

Extreme Heat Across the Pacific Northwest and Southwest

In addition to the storms, regions including parts of California, Washington, Oregon, and Baja California are facing extreme heat warnings. Temperature records have been broken across northwest Oregon and southwest Washington, and many areas are experiencing unseasonably high temperatures, with little relief at night. Tourists should be aware of the risks associated with extreme heat, especially in destinations such as Portland, San Francisco, and Vancouver, where overnight lows remain far above average.

For visitors planning to explore outdoor attractions, it’s vital to stay hydrated, wear light clothing, and avoid midday sun. Those heading to popular natural sites such as Yosemite National Park or the California coastline should be cautious of heat-related illnesses and be aware that some parks may implement temporary closures during peak heat periods.

Threat of Dangerous Waves on the Great Lakes

Lake Michigan is also experiencing life-threatening conditions, with waves up to five feet expected along beaches in northwest Indiana. Strong northwest winds have led to dangerous waves and currents, making swimming in these areas hazardous, especially for inexperienced swimmers. For travellers planning a beach holiday in the Great Lakes region, it is advised to stay out of the water and avoid venturing onto piers and jetties, where strong currents could pose a serious risk.

A Glimpse of Relief in the Southwest

While parts of the US and Canada remain under extreme heat advisories, there is some positive news for those heading to the Desert Southwest. The monsoonal storms could offer respite from the heat in cities like Phoenix and Las Vegas. Tourists should take advantage of the cooler temperatures and plan indoor activities during the peak storm periods. As the storm system weakens by August 25, the region will likely see a drop in temperatures, allowing for more comfortable outdoor exploration, especially in the evenings.

Hurricane Erin: Minimal Threat, but Coastal Areas Should Prepare

Meanwhile, Hurricane Erin is moving away from the US after a brief period of concern. Although the storm’s impact will be minimal, travellers to coastal areas should remain alert to potential risks. No major disruptions are expected along the US East Coast, and travellers planning to visit beaches or coastal cities should continue monitoring weather updates for any last-minute changes.

The Second Wave of Flooding: What to Expect

A second round of storms is expected to begin on August 27, potentially bringing more severe weather and flooding to parts of the US. AccuWeather has warned that multiple rounds of rain will target some of the same regions affected by earlier storms. Visitors planning trips to the Midwest and West, including cities like Kansas City and Oklahoma City, should prepare for flash flooding risks, especially in areas with already saturated soil. The National Weather Service has noted that this increased rainfall may lead to more runoff, raising the likelihood of flash floods.

For those planning to travel in these regions during the second wave, it’s advisable to have backup plans, as road closures and delayed flights are likely. Furthermore, it may be prudent to adjust outdoor excursions and explore indoor attractions such as museums, galleries, or shopping centres in cities like Denver and Dallas.
