Jessica has a paper round and was last seen carrying a yellow newspaper bag, though police are currently unable to confirm whether she was on her round when she went missing.
A Humberside Police spokesman said: "Police are concerned for her welfare as this is out of character for Jessica and she is believed to have been in a distressed state of mind when she left home.
"Specially-trained officers are conducting the search for Jessica with assistance from the Humberside Police helicopter and the underwater search unit."
Yesterday the RAF helicopter also joined the search.
Jessica was last seen in the Lincoln Way area of Beverley riding a pink bicycle and carrying a newspaper bag.
A bike has been found but officers said they can not confirm it belonged to the teenager.
She was wearing a dark blue/grey coloured zip up jacket, blue jeans, white trainers and a silver necklace with a St Christopher on.
She is described as 5ft 2ins, of a medium build and with shoulder length brown hair.
A Facebook group has been set up to help find Jessica, police said, but officers have asked members of the public not to conduct group searches at this stage.
