Floods & flash floods

Six inches of water moves a car. Twelve sweeps it away. The decisions that get travellers killed in floods are almost all made before the water arrives.

Sourcing policy

Every claim in a Safe Trip survival guide cites a source you can re-verify. We start from primary agency guidance (USGS, NOAA, FEMA, WHO, CDC, IFRC, country-level alert services), supplemented by peer-reviewed literature where the agency record is incomplete. Travel-blog content is never used as a source.

/sources lists every dataset feeding our country scores; /methodology describes how scores are computed.
