Due to the ongoing large fire at the Ocado warehouse in Andover, an evacuation will take place of properties within a 500-metre exclusion zone, and a 1.6km stretch based on the wind direction.
The reason for the evacuation is that there is a risk of toxic gas release or a large cylinder explosion.
A rest centre has been established at the Harrow Way Community School, for those who have been affected.
Numerous fire crews remain at the scene fighting the extremely challenging fire, including crews from Counties as far away as Oxfordshire, Hertfordshire and Kent.
Please heed all public safety messages from Hampshire Fire and Rescue Service, and Hampshire Police with regards to this incident.
Chief fire officer Neil Odin said the initial small fire had taken a “dramatic turn” early on Wednesday morning and firefighters had to be withdrawn.

A 500m “exclusion zone” has been set up as firefighters continue to tackle the blaze, which broke out on Tuesday morning.
Deputy chief fire officer Andy Bowers said the evacuation of Walworth Industrial Estate in Hampshire was a precaution to “keep the public safe”.
Mr Bowers said: “We have a risk of a toxic release or a large cylinder explosion.
“We are working extremely closely with all of our partners to keep the public safe.”
