Why on Sunday night, May 28 did they sound the flood warning ala

North Wildwood - Why on Sunday night, May 28 did they sound the flood warning alarm two hours after 17th Street already had over a foot of water on the street? Then to add insult to injury by sounding them again and calling our homes a half hour later? If it's an automated system, it's broken and needs to be fixed. If it's operated by a person, they should live on the island.
