Maybe CoCoRaHS should have more than one area where you can enter in duration information for multiple rounds of rain. The first round was the most intense and began around 5 AM. Heavy rain was falling at 5:30 AM and the rain did not tapper off until 7 AM. Lightning occurred less than or equal to a 1/5 of a mile away (you could not count seconds). 1.78 inches of rain fell in two hours. Round two began at 3:26 PM and lasted to 4:08 PM. Round three started at 5:33 PM and heavy rainfall was short and scattered over the period. The rain started and stopped until approximately 6:45 PM. 0.51 inches of rain fell in both rounds. I could not record each individual round due to the lightning.
