Impact & Risks

The expected low temperatures in the mid-50s°F (12-14°C) are not anticipated to pose significant risks to the general population. However, individuals sensitive to cooler temperatures, such as the elderly or those without adequate heating, should take precautions to stay warm during the night. The conditions may also lead to localized fog formation in low-lying areas due to the combination of cooling and residual moisture, which could impact early morning visibility for commuters.
