The National Weather Service reported minor flooding Saturday evening of the Pawtuxet River in Cranston and the Pawcatuck River in Westerly.
Both were still rising around 9 p.m., expected to crest overnight and then recede by sometime Sunday, meteorologist Hayden Frank said.
The Pawtuxet was expected to go as high as 11.1 feet, above its flood stage of 9 feet, which would result in moderate flooding. The Pawcatuck was expected to rise as high as 7.2 feet, just above flood stage of 7 feet, producing "very minor flooding," Frank said.
Rainfall totals in Rhode Island ranged from a high of 5.32 inches in Charlestown to a low of 1.58 inches in Chepachet, according to the latest weather service data.
Sunday is expected to be dry, but more rain is forecast for Monday night into Tuesday, which will bear watching, Frank said.
"A lot of times, when we get major flooding in New England, it's usually we have an event -- a big rain event -- and then a couple days later, we have another big event," he said. "Usually the first one primes you and the second pushes you over the edge."
