Expect more heavy showers and thunderstorms this evening, with potential rainfall of 10-20 mm and possibly up to 30 mm in less than an hour. Lightning and the chance of hail in some areas are also expected. The showers and storms will taper off later in the evening. Consider your risk of flash flooding and make a plan and emergency kit if necessary. Check road and public transportation conditions for possible delays, and prepare for power outages by gathering essential items. Seek shelter in a safe, enclosed space if you hear thunder while outside, and stay informed as weather warnings may change rapidly.
