The extreme weather brought by Storm Ciara and Storm Dennis has passed, but it is thought the destruction will take months to clear up.
Thousands of people suffered from unprecedented flooding across the country after sustained heavy rain caused exceptionally high river levels.
Towns like Pontypridd and Crickhowell were left submerged in water after rivers burst their banks in various areas.
Here are a few of the ways you can help:
The campaign smashed its initial target of £10,000 in just 24 hours, and has now raised nearly £30,000 from over 1,000 donors.

Pontypridd and Nantgarw
In Treforest, Pontyrpidd, a community centre is collecting everything from buckets to biscuits.

Places across the Rhondda, like Trehafod and Treorchy, were badly hit and thousands of pounds have been raised to help those affected.
Plaid Cymru AM Leanne Wood, who represents the Rhondda in the National Assembly for Wales, said: “The way communities in the Rhondda have pulled together, in adversity, to help those in need, has been absolutely astounding.”
It has also launched the largest ever food donation appeal. The council is calling on local supermarkets, businesses and residents to donate non-perishable items to provide food parcels to homes affected by flooding.
Donations for RCT Council’s food appeal can be dropped off at any of the Council’s libraries, or at the following council sites:
Llys Cadwyn (only on Wednesday February 26th)
Rhondda Cynon Taf Council has issued a warning, however, following a number of reports of people receiving unsolicited calls or online activity asking for flood relief donations.
The advice is to always ask for identification, and to confirm the legitimacy of anyone collecting or asking for donations.
