Dark Green Spotting on Washingtonia?

[MrTropical]

Hey everyone. I've had this Washy since June, and it's been flawless...until this morning.

For context, I'm located in coastal North Carolina and we're currently battling a nor'easter, so there's been frequent gusts of 40-60 MPH over the past 24 hours. One frond was broken off due to the gusty winds. But I also noticed something else. There is now dark green spotting on a few of the fronds. Is it wind-related? What caused this? I appreciate any input.

Could it be water absobsion from leaf creasing due to the wind? Sorry to hear about that nasty storm , they can make a mess of things in a hurry. Harry

To me it looks like a "crush" injury. Maybe something flying in the wind. Can even see where the leaf is physically deformed.

It looks like bruising.

@Harry’s Palms @jwitt @happypalms Thank you all for your replies. All are certainly plausible. We've received 2-3 inches of rain over the past 24 hours, which is less than initially forecast but plenty for water absorption to become an issue.

Also, my neighbor's house now has a section of siding missing due to the winds, and there is all sorts of debris scattered throughout the area. So I would not be surprised if something "hit" the palm during the night.

I agree that it is damage from harsh folding/creasing caused by the wind in the presence of moisture. Filifera is really susceptible to damage from wetness. That sensitivity gets worse when it drops below freezing.
