Local authorities provide ample warning and guidance in the event of a hurricane, so be sure to heed their advice. Don't underestimate the power of these storms.

Thunderstorms

Afternoon thunderstorms are common during the summer months. These storms can bring heavy rain, lightning, and strong winds.

It’s important to stay hydrated by drinking plenty of water, to wear lightweight and light-colored clothing, and to take breaks in the shade or air conditioning. Heat exhaustion and heatstroke are serious conditions that can occur when the body is unable to regulate its temperature. Be mindful of your physical activity and avoid strenuous activities during the hottest parts of the day.

Flooding

Heavy rainfall can sometimes lead to localized flooding, particularly in low-lying areas. It’s important to avoid driving through flooded streets and to be aware of potential hazards such as downed power lines. Pay attention to flood warnings and advisories issued by local authorities. Ensure that your property is properly protected from potential flood damage. Consider purchasing flood insurance if you live in a high-risk area.
