The summit level of the Royal Canal has been closed until further notice because of shortage of water and the 34th and 35th levels have been closed until 20 April for emergency repairs. Marine Notices here, along with a general waarning about low water levels.
Met Éireann’s Monthly Summary for March 2012 [PDF] says:
Rainfall totals were relatively low for the time of year, with percentage of normal values below 50% in most locations. Mullingar [which is on the summit level of the Royal Canal] reported its driest March since 1961 (51 years), while most other stations reported their driest March in at least 7 years. Number of wet days recorded (days with 1 mm or more) was below average everywhere, with most stations measuring their lowest March maximum daily rainfall in seven to 39 years.
Can we have our normal weather back please? Or will that be coming in the “summer” months?
