Y cyngor yw ei bod yn debygol iawn y gwelwn oedi hir a nifer o’r gwasanaethau trafnidiaeth gyhoeddus yn cael eu canslo. Gallai rhai ffyrdd gau oherwydd eira mawr, allai olygu bod cerbydau a theithwyr yn methu gadael. Mae’n debygol iawn y bydd tarfu ar gyflenwadau pŵer a chyfleustodau eraill am gyfnodau maith, yn ogystal â difrod i goed ac adeileddau eraill oherwydd eira trwm neu rew.
Advice is there could be long delays and cancellations of many public transport services seems highly likely. Some roads could become blocked by deep snow, potentially leaving vehicles and passengers stranded. Long interruptions to power supplies and other utilities are also very likely to occur, along with damage to trees and other structures due to heavy snow or ice.
