Jersey enters 'absolute drought' with supply concerns
Jersey entered an "absolute drought" after 15 days with no significant rainfall.
The company responsible for Jersey's reservoirs, Jersey Water, said the reservoirs were full but more dry weather could cause problems.
Howard Snowden, managing director of Jersey Water, said if the dry weather continued water reserves could suffer.
Jersey Met Department said an absolute drought was a period of 15 days with no more than 0.1mm of rainfall per day.
Mr Snowden said water demand was usually very high at this time of year.
He said: "Garden watering is very popular in Jersey and if we get a dry May we could get the highest demand in May rather than the summer months.
"We could be going into a very dry year, who knows, but from previous experience we know things can change very rapidly.
"We tend to get long dry periods followed by very short wet intense periods with a month's rainfall in two days."
