Last summer, our Stay Cool team organized and executed Heat Watch – a countywide heat mapping project – to understand heat distribution across Missoula County. Heat Watch data was collected on August 12th, 2025, and was coordinated by our Stay Cool Missoula team and partners from the Center for Collaborative Heat Monitoring, CAPA Strategies, and the Oregon Museum of Science and Industry. 

Salas said the kits are funded through a grant from the Center for Collaborative Heat Monitoring. They include items such as a water bottle, sunscreen, an instant cold pack and other supplies designed to help people stay safe in extreme heat.

Last summer, Memphis volunteers turned their cars into mobile weather stations and proved what a lot of locals already suspected: some neighborhoods are cooking. The one-day, community-run Heat Watch campaign clocked a high of 102°F and found roughly a 14.4°F gap between the hottest and coolest parts of the city.
