Rybuddion Tywydd

Helo gyfeillion y gwanwyn,

Mae’n amser diddorol i astudio ac arsylwi ar y tywydd! Bydd y rhan fwyaf ohonoch wedi gweld eira a gwyntoedd uchel yr wythnos ddiwethaf. Rwy'n deall bod llawer o ysgolion wedi'u cau, a hyd yn oed os oedd eich ysgol ar agor efallai ei bod hi’n rhy beryglus i gymryd darlleniadau tywydd.

Mae'n debyg byddwch chi wedi clywed pobl yn sôn am rybuddion tywydd dros yr wythnos ddiwethaf. Caiff rhybuddion tywydd eu rhyddhau gan swyddfa’r MET (gwasanaeth tywydd swyddogol y DU) gyda chod lliw (gwyrdd, melyn, ambr a choch) i ddangos pa mor eithafol fydd y tywydd mewn gwahanol ardaloedd.

Gwyrdd: dim tywydd garw.

Melyn: posibilrwydd o dywydd eithafol, gofalwch.

Ambr (oren): posibilrwydd cryf y bydd y tywydd yn effeithio arnoch chi mewn rhyw fodd, paratowch.

Coch: yn disgwyl tywydd eithafol, cynllunio ymlaen llaw a dilyn cyngor y gwasanaethau brys ac awdurdodau lleol.

Mae’r Swyddfa Dywydd hefyd yn defnyddio symbolau i ddangos pa fath o dywydd i’w ddisgwyl. Dyma symbolau yn dangos rhybudd coch am law, rhybudd gwyrdd am wynt ac eira, rhybudd ambr am iâ a rhybudd gwyrdd am niwl. Mae hyn yn golygu bydd hi'n bwrw glaw yn drwm a dylech chi baratoi am iâ. Beth am edrych ar y tywydd lleol ar wefan y Swyddfa Dywydd?

Yr wythnos diwethaf gwelodd rhai ardaloedd rybuddion ambr a choch ar gyfer gwynt, eira a rhew oherwydd storm Emma a’r 'Dihiryn o'r Dwyrain’. Mae swyddfa’r MET yn ein rhybuddio er mwyn i ni baratoi am dywydd garw. Gall tywydd garw (fel gwynt cryf ac iâ) achosi problemau a’i gwneud hi’n anodd teithio. Weithiau bydd ffyrdd, rheilffyrdd a hyd yn oed ysgolion yn cau oherwydd tywydd gwael.

Pa fath o dywydd weloch chi yr wythnos diwethaf? Os nad oeddech chi’n gallu casglu cofnodion tywydd, nodwch 'dim cofnod' ar y ffurflen, a dweud yn yr adran sylwadau pa fath o dywydd weloch chi! Gallwch chi hefyd roi gwybod sut hwyl sydd ar eich planhigion, ac a ydynt wedi blodeuo?

Daliwch ati gyda'r gwaith da gyfeillion,

Athro’r Ardd
