On Tuesday at 8:26 p.m. the National Weather Service issued a flood advisory in effect until 10 p.m. for Nassau and Suffolk counties.

“Minor flooding in low-lying and poor drainage areas,” explains the weather service. “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.”
Understanding the differences between advisories, watches, and warnings
- Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is imminent or occurring. If you are in a flood-prone area, move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
- Flood warning: Take action!
A flood warning is issued when flooding is imminent or occurring.
- Flood advisory: Be aware:
A flood advisory is released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that threaten life and/or property.
- Flood watch: Be prepared:
A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
