“Frequently asked questions — NSWWS improvements

…

Why are you making these changes?

The changes are being made following consultation over the past 12 to 18 months with the public and those with responsibility for protecting the public. In addition they address customer feedback from the public. The improvements reflect the latest requirements of warnings users.

What are the changes?

The key changes are:

….

Easier to understand
We will be making the warnings easier to understand by:

simplifying the language to make it less technical;
replacing the current Early, Flash and Advisory categories with Alerts (issued more than 24 hours ahead) and Warnings (issued up to 24 hours ahead)

Y llinell olaf yw’r un bwysig, dwi’n meddwl, gan ei bod yn gwneud yn glir bod yr ‘Alerts’ a’r ‘Warnings’ yn disodli’r system gynharach o gategorïau o rybuddion.

Mae enghraifft o’r ffordd y defnyddir (neu y defnyddid) y categorïau yma http://www.metoffice.gov.uk/about-us/who/how/case-studies/floods-2008

Anodd dweud. Mae'r Swyddfa Dywydd yn gwahaniaethu rhwng warnings neu 'rhybuddion' sy'n rhoi mwy o 24 awr, ac alerts neu 'rhybyddion brys' sy'n rhoi llai na 24 awr. Tybed a yw'r flash warnings yn llai na hynny hyd yn oed?

Yn iach,

Neu ydyn nhw'n defnyddio "flash" yma fel ansoddair gyda’r un ystyr â’r enw “flash” yn yr ymadrodd "news flash" ("fflach newyddion" yng Ngeiriadur yr Academi)?

Ar un wefan eiriadurol ceir “flash (adjective): that flashes; happening swiftly or suddenly: a flash warning”

Dw i gweld 'llifogydd sydyn' am 'flash floods'. Dw i'n cymryd mai at

lifogydd mae'n cyfeirio? Ond efallai nad hwnna ydi'r fersiwn swyddogol/

sefydlog.
