Ben complained of an odorous smell when he came in. Then I saw evidence of water near our monitors (our window cardboard cover had water damage that wasn't there when I left Friday) and we did a general inspection of the inside of the building: Found some water on top of two bins by the window by the clean room. Seems we had water leaking from the windows during the storm but hard to tell as it's been three-four days since it happened.
