Teams face a "difficult decision" tomorrow morning on whether to resume the search for the light aircraft Emiliano Sala was on, Guernsey's harbourmaster says.
A short while ago, today's search was suspended.
Captain David Barker says the likely area where the plane could be found is ever expanding.
"It gets to the point where it's impossible, even with unlimited resources to search that area."
"The weather forecast for tomorrow is not as good as today, so we will be making a very difficult decision in the morning whether we can carry on with the search or not," Captain Barker added.
The plane left Nantes in north west France at 19:15 on Monday evening and had been flying at 5,000ft when it contacted Jersey air traffic control requesting descent, Guernsey Police said.
The plane lost contact while at 2,300ft and disappeared off radar near the Casquets lighthouse, infamous among mariners as the site of many shipwrecks, eight miles (13km) north-west of Alderney.

Emiliano's father Horacio revealed he heard the news from a friend.

"I'm desperate. I hope everything goes well."

John Fitzgerald, chief officer of the Channel Islands Air Search, told BBC News earlier that the probability of finding anyone alive from the missing aircraft was "reducing very rapidly".
"I think with the sea temperatures and the sea conditions the chances of finding anybody alive are reducing all the time," he said.
"The sea temperatures are very, very cold and just sap the core temperature of anybody in the water very, very quickly."
