A UN agency has expressed concern about the upcoming winter season. Nearly 1.8 million people will have little protection from harsh weather conditions, including rain, flooding, and cold.

The situation is described as grim, with a lack of adequate shelters being a major issue. Further details about the situation and the affected population are available from the source.

The UN agency's statement highlights the need for protection and shelter for a large number of people, but does not provide additional information about the circumstances or potential solutions.
