The 48-year-old was last seen this morning (Thursday 29 June) in the Beech Crescent area of Hythe and has been out of contact since.
This is out of character for Susan, and her family are growing increasingly concerned for her welfare.
Susan is described as:
5ft 5ins tall
Short grey hair
She is likely to be wearing jeans, a hooded top and trainers, but may also be wearing a blue One Stop T-shirt.
Susan is believed to have driven off in her car, which is described as a white old-style Honda Civic. The registration number begins with P739.
Poice are asking members of the public to share this across Hampshire, as she may have driven some distance away from Hythe.
If you see her please contact police immediately on 101, or call 999 if it is an emergency.
