Any tips on ensuring the survival of my 80 foot Washingtonias - Louisiana once in a lifetime snow storm

[LouisianaWashingtoniaRobus]

I wrapped the base of my palms with blankets before the snow started. Temperatures might be as low as 13 degrees tonight for 2-3 hours. 

Does anyone have any tips or knowledge as to whether they will be okay? 
 

posting pics from last night when I wrapped versus today in the snow. We have gotten about 10 inches so far. 
 

love these palms and really hope they’ll be okay!!

I'm sorry to say but the wrapping you did is absolutley no help. The critical part of the palm (the bud/growing point) is 80 feet up in the air as you say, so not practical to protect.

Honestly there is nothing you can do at this point but hope they survive. The trunks on your palm are not the super ultra skinny kind so I'd say there is a decent change they mnake a comeback.

Thanks for your feedback!! Should I remove the blankets? Are they hurting at all?

Those blankets aren't doing anything.  Like Xenon said, the most critical part of the palm is the heart, or bud which looks to be around 30 feet or so up.  

Those palms are going to experience some damage.  If the temperature stays mostly above 20F with only briefly getting into the teens, then they should make it.  Hit them with some fertilizer before the summer, that will help them recover before next winter.

Thanks for the feedback, really helpful. It will be below 20 degrees for a 12 hour period tonight where it’s now forecasted to get as low as 9 degrees 😳

Yikes.  I wish you good luck.  Yeah you might lose them in that cold, or maybe not.  Just take good care of them when it warms up.

I’ve been following the predicted lows in Louisiana, that heavy snowfall is leading to near 1989 temperatures along the coast. Possibly colder. Someone sent me this weather map . Good luck.
