Snow caused problems on the roads after falling overnight.
Some vehicles were left stranded on the A4109 between Seven Sisters and Banwen in Neath Port Talbot, while the A482 in Lampeter, Ceredigion, and A4221 between Abercrave and Coelbren in Powys were blocked for a time.
BBC Wales weather presenter Derek Brockway said "a huge swirl of low pressure" was causing the unsettled conditions.
The reason for the wind, rain and snow over southern Britain today is a huge swirl of low pressure. Unsettled weather for much of Iberia, France and Belgium too. pic.twitter.com/p7qLfe5U1U— ᴅᴇʀᴇᴋ ʙʀᴏᴄᴋᴡᴀʏ ᴡᴇᴀᴛʜᴇʀᴍᴀɴ (@DerekTheWeather) November 14, 2019
