Why it matters

The unseasonably warm temperatures will provide a welcome boost to businesses and residents in the region, allowing them to enjoy outdoor activities and dining during the spring season. However, the extreme heat could also pose risks, especially for vulnerable populations, and may have implications for energy usage and water resources.

The warm weather is a departure from the region's typical spring conditions, and could have both positive and negative impacts on the local community.
