1. A system, comprising a computer including a processor and a memory, the memory storing instructions executable by the processor programmed to:
upon determining a mobile object is approaching an ice layer above a body of water, obtain a thermal image of the ice layer;
input the thermal image and ambient temperature data to a neural network that outputs a plurality of regions of the ice layer and respective estimated thicknesses for the regions;
determine a classification for each region based on its estimated thickness and the mobile object, wherein the classification is one of preferred or nonpreferred;
predict a future time at which the classification for one region will transition between preferred and nonpreferred based on a characteristic of the mobile object and predicted ambient temperature data; and
output the classifications for the regions.
