• Public transit and freight transportation may be impacted by unfavorable road conditions, including localized waterlogging and reduced visibility. Businesses reliant on the timely transport of freight through the affected areas are likely to face delivery delays.
• The heatwave poses risks to public health, particularly for vulnerable populations, such as hypothermia-related illnesses such as heat stroke and heat exhaustion.
• Operational disruptions may arise from the extreme heat, affecting outdoor activities, labor, and potentially increasing strain on power grids due to higher usage of cooling devices, potentially causing power outages.
