The extreme heat poses significant risks to public safety, particularly for those engaging in outdoor activities within the affected areas. High temperatures can lead to heat-related illnesses such as heat exhaustion and heatstroke, especially for hikers and outdoor enthusiasts. The closure aims to mitigate these risks by restricting access to vulnerable areas. Non-compliance with the closure order could result in penalties, including fines of up to $5,000 for individuals or $10,000 for organisations, and potential imprisonment.
