...March 2018 was generally drier and less snowy than normal...

For the most part, Southeast Alaska recorded anywhere from one half
to only one third of the normal March precipitation values. The
ongoing lack of precipitation has resulted in Southeast Alaska being
labelled as either abnormally dry or in moderate drought according
to the national drought monitor. This is particularly noteworthy
considering nearly all of Southeast Alaska is also considered a
temperate rainforest. While a short term precipitation deficit does
not equate to climate change, the multi-year precipitation deficit
currently being experienced by Yakutat could very well be the result
of climate change. For the remainder of Southeast Alaska, the
current situation bears watching for any long term or seasonal
trends.

In spite of the general snowfall and precipitation shortfall, there
were a few notable extremes. Juneau airport, which recorded 33
percent below normal March precipitation, recorded 67 percent above
normal snowfall for the month. Meanwhile, Little Port walter, one of
the wettest places in Southeast Alaska, saw twice their normal March
precipitation, but less than half of their normal March snowfall.
Yakutat was both dry and lacking in snow for the month, recording
only a third of their normal March precipitation and snowfall.

Several record high temperatures were set across the Panhandle
between the 12th and the 15th of the month. During that time,
temperatures rose to the mid 60s on multiple days. Record daily
snowfall was also set in Juneau on the 26th of March.
