As Boise residents prepare for Fourth of July festivities, the National Weather Service is forecasting temperatures nearing the triple-digit mark. The extreme heat is expected to persist throughout the holiday, creating potentially hazardous conditions for outdoor events and traditional fireworks displays.

Local officials are advising the public to prioritize heat safety by staying hydrated, seeking shade during peak afternoon hours, and checking on vulnerable neighbors and pets. Those planning to attend public gatherings should prepare for high heat indices and consider adjusting outdoor activities to the cooler morning hours to avoid heat-related illness.

Key Heat Safety Tips for Independence Day:

* Hydration: Drink plenty of water throughout the day, even if you do not feel thirsty.

* Sun Protection: Wear lightweight, light-colored clothing and apply broad-spectrum sunscreen frequently.

* Schedule Adjustments: Limit strenuous physical activities and fireworks setup to the early morning or late evening.

* Cooling Centers: Be aware of local indoor spaces with air conditioning if you do not have access to a cool environment at home.

* Pet Care: Ensure pets have access to ample shade and fresh water, and avoid walking them on hot pavement, which can burn their paws.
