Prince George’s County officials are assessing the damage caused by storms Friday evening to determine if enough harm was done to merit federal aid.

A microburst — a small, intense downdraft similar to a tornado — hit the Bladensburg and Cheverly areas on Friday evening. Since then the county’s Department of Environmental Resources have inspected 126 structures so far, 21 of which they deemed unsafe and uninhabitable. County officials are asking residents to call in reports of structural damage in those areas the microburst impacted.
