Information on Laplace needed

[BananaTom]

Brother in law and sis in law are in Laplace on the 2nd floor / level of their home, with about 2 feet of water on the inside of the first floor / level. It appears they will wait it out. They have little means of communication. Their phone just started sending text messages.

I am in Pensacola feeding them information, what little I can learn from here. I believe the water came from Lake Ponchatrain, therefore, the water will recide when the wind shifts. Am I correct?

Or is the water from rain, or both.

Trying to figure out when the water will go down

I know the National Guard is all over Laplace, and have informed them of same.

They are at 63 Country Club Drive.

Thank you
