The departure of the nor’easter marks the end of the recent period of heavy rain and strong winds in the Boston area. While the storm is no longer a significant threat, residents should remain cautious as there is a chance of showers on Friday night and Sunday. The recent heavy rainfall may have left some areas prone to minor flooding, so those in low-lying regions should stay alert. The warming trend will provide a brief respite, but cooler temperatures are expected to return by the weekend.
