Richwood has most certainly been flooded in the past. Hurricane Harvey impacted 622 Richwood properties in September 2017 as a result of the water. Find out more about previous floods. According to the rebuilt flood model from this cyclone, flood water reached roughly 622 houses in Richwood. However, that does not mean that all 622 houses were destroyed. In addition to the hurricane-related flooding, rain-related flooding is also common for this area. Since 1950, there have been over 20 inches of rainfall at Houston's Kennedy Airport, more than six feet above average. Flooding related to rain events occurs when waterways such as creeks and rivers overflow their banks due to heavy rains. The National Weather Service predicts that more severe storm-related flooding will be likely in the coming years due to climate change. As temperatures increase, so too will the amount of moisture in the air. This leads to more intense precipitation events with more water pouring into already saturated ground environments like those found in Richwood. Flooding can be fatal if residents aren't warned in time to take action. If you're living in or near an area prone to flooding, make sure you know what signs to look for in order to prevent death or serious injury. For example, if you see trees down on your property or along the road, it may indicate that a tornado has passed by. Contact local authorities immediately if you think someone might be in danger of drowning.
