Many state and county roads across Long Island remain impassible due to flood damage.
According to the National Weather Service, Stony Brook saw nearly 10 inches of rain.
Officials say they expect there will be more damage as they continue to inspect infrastructure across the town.

Another video from Port Jefferson showed an apartment complex inundated with water.
Parts of the Long Island Expressway were shut down earlier as the workweek began, with crews rushing to clear the roads.
Superintendent Losquadro said crews will continue to inspect infrastructure across the town.
"Do not travel unless absolutely necessary and never try to drive through standing water," he warned. "Many road endings across the North Shore have suffered serious damage or collapse as well."
Stony Brook University student move-in plans canceled
The severe flooding prompted Stony Brook University to cancel student move-in plans scheduled for Monday and Tuesday.
"We are still assessing the damage to campus caused by the overnight storms and flooding," Lawrence Zacarese, Vice President for Enterprise Risk Management and Chief Security Officer at Stony Brook University, said Monday in a campus emergency alert.
The fall semester is still scheduled to begin as planned next Monday, Aug. 26, according to the university.
Long Island beaches
Several beaches in Suffolk County remain closed due to high levels of bacteria in the water.
According to the Department of Health Services, these levels could exceed New York State standards.
These bodies are heavily influenced by stormwater runoff and so officials have issued against bathing and other water contact for at least 24 hours after the rain has ended.
