Logan Township Police Chief Ron Heller said he expects to levy fines under the state's new emergency regulation, that went into effect in September, that charges motorists steep fines for ignoring emergency road closures.
If rain continues as expected, several major Logan Township roads could be closed, he said.
"Every time [roads are closed], we've had somebody drive through it," Heller said. "And every time we have someone drive through, they get stuck in it."
Plank Road near Kmart, Logan Boulevard near Spruce Street and Old Sixth Avenue near Sandy Run Road are all common flood risks and susceptible to closure, Heller said.
Should police close those roads, the new law would allow fines up to $250 - or $500 if emergency responders are needed. Offenders also get two points on their licenses. Motorists ignoring signs are also responsible for expenses related to their rescue, according to the law.
"The reason that so many people drown during flooding is because few of them realize the incredible power of water," the National Weather Service's Turn Around, Don't Drown campaign website said. "A mere 6 inches of fast-moving floodwater can knock over an adult. It takes only 2 feet of rushing water to carry away most vehicles. This includes pickups and SUVs."
