Wrth reswm, bydd yr angen i griwiau yrru’n arafach ar yr eira ac ar ffyrdd rhewllyd wedi effeithio ar yr amser yr oedd ambiwlansys yn ei gymryd i ymateb i alwadau - roedd llawer o’r is-ffyrdd a’r ffyrdd ymyl ar gau am fwy nag wythnos - o ganlyniad, roedd hi’n anodd cyrraedd y safon o ran ymateb o fewn 8 munud. Yn wir, mewn rhai achosion, roedd yr amodau ar y ffyrdd mor ddifrifol fel bod angen gofyn am gymorth y Gwasanaeth Tân. Gadewch i ni fod yn glir, roedd yr amodau hyn yn rhai anodd i bawb.
Naturally ambulance response times will have been affected as crews needed to reduce speeds on the snow and icy roads  - with many of the minor and side roads impassable for more than a week - and as a result the 8 minute response time standard was difficult to achieve. So severe were the road conditions that in some instances the Fire Service were called out to assist. Let us be clear, these were difficult conditions for all involved.
