They say that the maples have increased their intensity to what many believe will be their peak colour.
High winds forecasted for early next week are expected to increase the number of leaves falling from the trees.
Brighter leaf colour will mean a busy weekend with visitors. Those travelling to the Park to see colors are advised to plan ahead.
Fall colour is subject to numerous environmental variables such as daylight length, moisture, temperature, frost, wind and heavy rain, so the exact peak of fall colour is difficult to determine in advance.
High winds, rain, or even snow can sometimes quickly result in fragile leaves being knocked off the trees increasing leaf fall.
