Long rains late

April was another month of net ablation. There was a small snowfall event which began late in March (see 4/10 entry below), but otherwise there was only a few cm on ~21 April.

May could turn out to be snowy however, as it did in 2003 and 2007 following dry March and Aprils. Conversely, the long rains were finished entirely by this time in 2002, 2004 and 2006 - and failed completely in 2000.

At any rate, for the previous 12 month interval, mass balance on the Northern Ice Field has easily been the most negative of the decade.
