| Narrative: |
|
|
|
Due to a very low precipitation
month and the excessive cold that we have been experiencing, |
|
| our snowpack
for the Wasatch Front dropped 12% of normal to 98%. The lower elevational bands are |
|
| showing a
large percent of normal due to such cold weather that is retaining this
shallow snowpack from |
|
| melting. With March yet to come and a very stagnant
high pressure looming for the first part of the month, |
|
| it
looks like a slightly below normal runoff can be expected for 2002. I anticipate the runoff will be timed |
|
| very
late in the normal sequence due to the unusually low temperatures that have
been seen all winter which |
|
| will be
keeping densities low through snowmelt.
March usually brings some maritime climate |
|
| precipitation
with it in which influences data dramatically if we miss it or get it. My guess is that we will get some very |
|
| wet storms
toward the end of the month of March to bring us back to or exceed normal
come my April 1st Snow Survey's. |
