Subtropical Storm Alberto indirectly brought torrential downpours and thunderstorms to the Mid-Atlantic Region. While Alberto did not go straight over the region, a flow of moisture was moving northeast coming from Alberto. The northeast flow moved towards a stationary front that was sitting over the Tennessee Valley and the Mid-Atlantic region. These were the ingredients for the destructive flooding that occurred in Maryland, Virginia and North Carolina.
Ellicott City in Maryland was under water on Sunday, May 27, 2018 when a nearby river overflowed its banks and into the streets of local homes and businesses. Many people needed to be rescued from buildings and vehicles as the force of the water pushed vehicles down the streets. One person lost his life when he was attempting to help a person in need. The above image is from Syria, Virginia where a woman and a young girl were swept away in the flooding. The young girl was quickly found; however, the woman has yet to be found as of the time this article was posted. The image on the top used to be a bridge where people could walk, but the strength of the flooded waters pushed the bridge off and you can see it in the image on the bottom. On Route 33, in Central Virginia, a landslide covered the highway prompting several road closures and detours. If we continue south, North Carolina had its share of landslides and flooding. One landslide compromised the integrity of the Lake Tahoma Dam in North Carolina prompting evacuations. Some areas have received over 6 inches of rain and the threat of rain continues. Many roads have been closed throughout the Mid-Atlantic due to debris and flooding.
Always remember; if you see high water, turn around, don’t drown. It only takes 6 inches of water to stall a vehicle while a foot of water will float many vehicles. Once the water level reaches two feet, your vehicle will likely be carried away. Flooded waters are typically muddy so any debris lurking in the water may not be visible.
Alberto is no longer a threat, but rain will persist through the weekend. With already saturated soil, any additional rainfall will produce more flooding. After the first weekend of June dry weather will make its way back into the area.
