An overnight search involving 40 officers, dog handlers and mountain rescue teams has failed to find April Jones, police have said.
The five-year-old was abducted from near her mid-Wales home at around 7pm on Monday and hundreds of people have joined the search for the missing youngster.
Superintendent Ian John of Dyfed Powys Police warned of the "challenging conditions" facing search and rescue teams and asked members of the public to leave today's search to "members of our trained and skilled teams".
A 46-year-old man, named locally as Mark Bridger, remains in police custody after being arrested yesterday on suspicion of abduction. He is known to April's mother Coral and father Paul.
On Tuesday night in a statement her family said they had been left "shattered" by the abduction.
