Backpackers already in Laos or those looking to head to the country in the near future have been warned that the Mekong River has risen above flood levels.
The country is a popular destination with gappers, particularly as a short break as part of a longer stay in Thailand or other regions of south-east Asia.
However, the Foreign and Commonwealth Office (FCO) has confirmed that several areas of the capital, Vientiane, are already subject to flooding.
The Thadeaua Road area and places near Wattay airport have been affected, while large sections of agricultural land are being submerged in Bokeo, Xaignbouri, Luang Prabang and Vientiane provinces.
The FCO has issued the following advice to travellers: "You should avoid areas near the flooding, and reconsider travelling by small river craft on the Mekong River.
"If you are in low-lying areas near the Mekong River, and it is safe to do, you should move inland as a precautionary measure until the current floods subside.
"If you are trapped in an affected area, you should remain in a safe location until the flooding subsides."
Most observers are expecting water levels to rise gradually over the coming days before they recede, but the sudden nature of the flooding shows the importance of having backpacker travel insurance in place to cover contents against damage.
