The top petroleum analyst at GasBuddy said Tuesday gas prices are dropping at a rapid clip and it's not just a West Michigan phenomenon. reports the average retail price for a gallon of regular unleaded gasoline dropped below $3.60 for the first time since April 10.

Patrick DeHaan, senior petroleum analyst for GasBuddy, says prices have dropped each day nationally for the past 18 days. He said crude oil prices have declined, and with that comes less pain at the pump.

"West Coast consumers will likely see their retail prices slide from 15 to 25 cents per gallon over the next two weeks, and across the rest of the country we can expect prices at the pump to shed from 10 to 20 cents per gallon," he said.

Regionally, gas prices were reported to GasBuddy as low as $3.35 for a gallon of regular unleaded gasoline.  GasBuddy reported a state average price of $3.61 per gallon.
