This could be a critical weekend in the coronavirus pandemic, as University of Washington data shows the country will possibly reach its peak death rate on Sunday.

With that possible peak only increases the importance of practices like social distancing -- but is Long Island adhering to that? Officials say yes, for the most part, and it's saving lives.

But medical professionals say those who are not taking social distancing seriously are placing the public in jeopardy.

"I cringe, I absolutely cringe I don't understand at what point and how many deaths do we actually have to see before people understand and take this seriously," says Dr. Evelina Grayver.

And yet, parking lots are packed, supermarkets are jammed and open spaces are crowded.

At Cold Spring Harbor State Park, the parking lot is usually empty, but on Friday it was packed with people hitting the trails.

Nassau County Executive Laura Curran says they have received hundreds of calls from residents reporting people are getting too close to each other.

"We are getting a lot of complaints about parks and people being out. Most people are doing the right thing, however if you are not, you will face seriously consequences," says Curran. "The fines from the fire marshal can be up to $5,000 each."

Curran says if people let up on social distancing, the virus can come back with a vegance.

Suffolk police say they have also answered hundreds of calls made to the county's 311 hotline for social distancing complaints.
