I live in the Ft. Lauderdale area and Myrtle Beach is similar weather to us.
My best guess will be afternoon rain/t-storms. I had years where we had a 3-4 hour t-storm
delay and still finished the round by 5-6 PM. I have extra pair of shoes and clothing in my vehicle, rain gear and rain gloves in my bag for every round just in case. Leaving Saturday and hoping for the best. Ken Weatherford, I will see you Sunday at Dye Club, you are in my group.
