Flames are spreading rapidly along the boardwalk in Seaside Park at the Jersey Shore and smoke can be seen for at least 7 miles in the area.
"I see thick, billowing, black smoke with ruby red flames. It's still raging out of control," says Justin Auciello, of Jersey Shore Hurricane News.
The fire, which started around 2:30 p.m. near Kohr Brothers Frozen Custard shop, 1800 Boardwalk, has now destroyed at least 80% of the boardwalk in Seaside Park. That's according to Seaside Park's Police Chief, Francis Larken, who also says possibly three dozen businesses have also been destroyed.
"This is obviously just an unthinkable situation, for us to be standing here and watching this, what's going on behind all of you is just unthinkable," says NJ Governor Chris Christie, who added that when he first heard the news he told he staff 'I feel like I want to throw up' after all the work this area did to rebuild.
Gov. Christie estimates 400 firefighters are on the scene. Those crews have cut a 20-foot wide trench along the the boardwalk at Ocean and Lincoln Avenues, in the hopes of stopping the fire from spreading.

Everything south of the trench is expected to be a total loss, says Christie. They are trying to save as much as possible north of the trench.
Christine Hemingway was working inside Kohr Brothers this afternoon and says it appears the smoke was rising from underneath the boardwalk.
"Our manager came running through the stand and said 'get out,' we go around the corner in front of Biscayne Candy and there was smoke coming up from the boardwalk," says Hemingway. "There was a little smoke and then all of a sudden, it got real thick and black."
Strong winds, whipping at speeds of 20 to 30 miles per hour, are presenting the biggest challenge for firefighters who have been called in from neighboring NJ counties.
"It's an all call, which means anybody that has equipment [in Ocean County] are asked to respond," says Al Della Fave, of the Ocean County Prosecutor's Office, who is handling calls for the Sheriff's office while they are on scene. That means up to 33 municipalities can respond.
"It's all hands on deck and they're doing the best they can, but the winds are really making it difficult," says Della Fave.
Embers have blown for at least 8 blocks, igniting a fire at a nearby condominium complex at Sumner Avenue and Ocean Terrace, which was quickly put out. Those embers have also landed on area homes and businesses.

Nancy O'Brien runs EJ's Dance Club at 919 Boardwalk, which is about a mile and a half from the fire. Even at that distance the smoke is a real nuisance.
"It's pretty acidy. Our eyes are burning. It's very, very windy," says O'Brien.
The area of the boardwalk between Stockton and Farragut Avenues, in front of Funtown Pier, was not destroyed during Superstorm Sandy. But the pier itself was, becoming a symbolic image of the storm's destruction.
An estimated 90% of the 33 rides on Funtown Pier were lost in the storm. The pier, which was not open this Summer, is now fully engulfed in flames, destroying the small portion that was left standing after the storm.

"It's just devastating to the area. It's just heartbreaking to see. After what we just went to almost a year ago, and now this. I'm just in disbelief and shock over this. I can't believe it, " says Larkin.
The fire has also spread to at least four blocks of the boardwalk in neighboring Seaside Heights, which was destroyed by Sandy and then rebuilt.
Several firefighters have suffered minor injuries, mostly heat exhaustion and smoke inhalation.
A spokesman for New Jersey Natural Gas says they've isolated gas service just to the boardwalk area and no residents have been affected.
