We have been speaking to Shirley Pumfrey, a resident who lives near the harbour mouth.
She says she initially saw a few ambulances before more and more arrived, and then the helicopters landed on the beach.
"I have never seen them do that. The whole road was just full of emergency services," she says.
"It was horrific and quite scary to see that many."

Reporting from Shoreham
A number of vehicles have left the scene now but the road is still cordoned off and a short while ago there were still seven or eight ambulances in the area.
I live in the area and it kicked off at about 15:00 BST when I heard helicopters circling.
It's certainly one of the biggest emergency service responses that I have seen in a long time.
A spokesperson for Shoreham Port says it is "working with multiple agencies regarding this incident", which emergency services were called to at about 15:00 BST.
It added that it "would urge the public to avoid the area".

We've been hearing from a nearby resident, Pete Book, who says he was "walking home from the pub" when he "saw and heard the Coastguard helicopter circling over the lifeboat station on the beach".
"As I neared home, a yellow air ambulance helicopter landed. There were a lot of ambulances, Coastguard and police vehicles converging on the area, and the coast road was closed," he says.
Book adds: "An orange-and-white air ambulance then landed, and the Coastguard helicopter flew off."
He says the road is still closed, and there are still "lots of emergency responders and helicopters at the scene".
"The lifeboat had also launched and was being returned to the station."
The A259 is closed in both directions due to the emergency services incident, between New Road and Kingston Lane.
The street is a main commuter road between Brighton, Shoreham and Worthing on the South East coast, and further into West Sussex.

It is very clear that this is a huge emergency operation taking place in Shoreham.
We have had a number of statements from emergency services including Sussex Police. It is very clear that it is a massive emergency service response with a number of agencies supporting the operation.

A spokesperson for the Air Ambulance Charity in Kent, Surrey and Sussex (AAKSS) says it sent both of its helicopters and critical care team to the scene of the incident today "as part of the coordinated emergency response".
