Isabel and the recent derecho had stronger winds. A couple semaphores/street lights were out on 355 this morning near Montgomery Village Ave. Saw a large twig/small branch of small diameter down on Mont. Village Ave this morning from storms last night. Tree near gage could have shielded the gage from some of the rainfall it should have caught.
