People in north-east Hampshire were being advised to stay indoors on Saturday evening after a freak storm brought down trees across the county.
Hampshire Constabulary said "very strong winds" led it to issue the warning for Hart and Rushmoor.
The force said: "We are advising residents in the north of the county to be very careful if they are out and about this evening.
"Consider staying in and if you do go out, slow your speeds on the roads in case of fallen trees and debris."
One tree came down on a car in Fleet Road, Hartley Wintney, with eyewitness Laura Wiles describing the occupants as "lucky to be alive".
She posted on Twitter that the two occupants were "fine", adding: "Thanks to fire brigade, ambulance and police for their fantastic response to the crushed car on Fleet Road."
Trees fell on railway lines across the South West Trains network, and Farnborough South county councillor John Wall described the travel situation as "chaos" as he waited for a train at Woking station.
Aldershot Town's home match at the ESS Stadium against Halifax Town managed to make it through 90 minutes, with the ground staff and volunteers being praised for "getting the covers off and the game on".
