Don’t clean the bike just yet. A heavy rain event is on the way tonight that could leave 1-4″ by Friday morning. The main event comes early Thursday as a sluggish cold front treks across the state. It’s not the intensity of the rain but the duration of a good, steady rain for about 3-6 hours tonight that could lead to flash flooding…and muddy trails.
Flash Flood Watch until Thursday afternoon
Rainfall: 0.5-4" through Friday morning
Based on the current soil moisture conditions it would only take 3.0″ to 3.5″ of rain to cause flooding. I would bet the trail conditions will be too wet for riding later this week.

Hey, it could be worse. You could live on Mt. Waialeale, Kauai, Hawaii, arguably one of the wettest places on Earth, where 384.35” of rain falls a year. There has been some debate recently within the meteorology world about the wettest place on Earth. Many of these rain soaked locations are extremely remote without any reliable weather data collection. It now looks like Hawaii may have been dethroned as the wettest spot. Weather Historian Christopher C. Burt did a little digging to nail down the top ten wettest places on Earth. Some of his findings may surprise you.
Also be glad you don’t live in Miami, FL. On Tuesday, Miami International Airport recorded 9.7″ of rain! What’s even more impressive is that 4.4″ of that fell in just one hour! Talk about a tropical downpour!
