A spokesman for Highways England said on Twitter: "The A282 eastbore tunnel (northbound) at Dartford Crossing is closed.
"This is in preparation for a full closure of the QEII bridge (southbound) as a result of strong winds.
"Traffic heading south will travel contra-flow in the eastbore tunnel. Updates to follow."

Why does the Dartford Crossing have to close?
Motorists who use the crossing often will know how frustrating it can be when it is closed.
But the Queen Elizabeth II bridge must shut if there is a risk to the safety of drivers.
And periods of high winds are one of these risks.
Highways England's protocol sets out when exactly they have to close the Dartford Crossing.
The protocol ensures motorists are protected against possible accidents which can be caused by high winds.
Here are the three precautions they take:
When the crosswind speed reaches 50 mph or the headwind speed reaches 60 mph, speed limit signs at the crossing will reduce to a limit of 30 mph.
Lane closures are introduced if the crosswind speed reaches 55mph or the headwind speed reaches highs of 65mph.
If the wind is from the east, lanes two and four will be closed; if the wind is from the west, lanes one and three will be closed.
When crosswinds reach over 60mph, the QEII Bridge completely closes to all traffic.
All these precautions can be kept in place until high winds have passed.
A spokesman for Highways England has previously talked about the protocol in place which will deem the crossing unsafe for motorists when it comes to wind speeds.
The spokesman said: "When the crosswind speed reaches 50 mph or the headwind speed reaches 60 mph, the matrix and variable speed limit signs at the crossing will be activated to show an advisory limit of 30 mph.
"When the crosswind speed reaches 55 mph or the headwind speed reaches 65 mph, lane closures will be introduced.
"If the wind is from the east, lanes 2 and 4 will be closed, if the wind is from the west, lanes 1 and 3 will be closed.
"When the on-site anemometers and Met Office forecast predicts the crosswind speeds increasing to over 60 mph, the QEII Bridge will be closed to all traffic."
