At 2:44 p.m. on Saturday, the National Weather Service released a coastal flood warning valid from Sunday 10 p.m. until Monday 4 a.m. for Suffolk and Nassau counties.
“1 1/2 to 2 1/2 ft, locally 3 ft, of inundation above ground level likely in vulnerable areas near the waterfront and shoreline,” can be expected according to the weather service. “This water level forecast will be highly dependent on timing of windshift from northeast to north storm force winds with respect to the time of high tide, and will be refined over the next 24 hours. Ice cover in the bays and harbors could exacerbate flooding and cause damage to north to northeast facing shoreline structures. Additional minor to locally moderate coastal flooding possible with the Monday afternoon high tide.”
The weather service comments, “Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth.”
Understanding the differences between advisories, watches, and warnings
- Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is either imminent or already occurring. In flood-prone areas, it’s crucial to move immediately to higher ground. A flash flood is a sudden and violent inundation that can develop within minutes to hours, and it can even happen in areas not currently experiencing rainfall.
- Flood warning: Take action!
A flood warning is declared when flooding is on the verge of happening or is already underway.
- Flood advisory: Be aware:
A flood advisory is issued when flooding is not expected to be bad enough to issue a warning. However, it may cause significant inconvenience, and if caution is not exercised, it could lead to situations that may threaten life and/or property.
- Flood watch: Be prepared:
A flood watch is issued when conditions are favorable for flooding. It doesn’t guarantee that flooding will occur, but it signifies that the possibility exists.
