Recent rain from Fay and Hanna have definitely helped with the drought in central Virginia. Here are the rain totals so far this year in Richmond. You can see that we are well above normal and way above the total from last year.
Things are not looking as good for some communities to the east of I-95. I got an email from a viewer in Toano who said that they only received .75" from Hanna and need more rain. However, conditions to the southwest are even worse. These areas saw almost no rain from Hanna! Looking at the current stream flow of rivers across the area, you can see a lot of red dots indicating flow that is well below normal in that region.
Drought conditions can have a major impact on fall foliage. During the summer, moderate temperatures and above normal rainfall will yield the brightest colors. So if this trend continues, the colors could be affected in areas around Roanoke, Blacksburg and farther west.
