Foliage Freeze
Foliage Freeze : Branches, needles or leaves on green vegetation that have been dried by a fire leaving them fixed in position to point in the direction of the wind at the time of the fire's passage. Visually the vegetation takes on a windswept appearance. Foliage freeze is only an accurate indicator of wind direction; however, this will generally coincide with direction of fire spread within the areas of advancing fire progression
