Degree Days above 32°F
(DD32)
TODAY'S DD32: 23
18-DAY CUMULATIVE DD32: 369

DD32 is calculated as: DD32 = TMAX - 32
18-day Cumulative DD32 is the sum of DD32 for the last 18 days.
Precipitation at Paradise DAY 1: 0.00 in
DAY 1-3 (P3): 0.27 in
DAY 4-15 (P15): 3.02 in
18-DAY TOTAL (P18): 3.29 in

PRECIP THRESHOLD A (PA) EXCEEDED: False
P3 > (-0.67 * P15 + 2.5)

PRECIP THRESHOLD B (PB) EXCEEDED: False
P3 > (-0.67 * P15 + 4.5)
Snow at Paradise DEPTH: 62 in
SWE DAY: 180
CALCULATED SNOW DENSITY: 451.45 kg/m3
CALCULATED SWE: 28.18 in

SWE Day, Calculated Snow Density, and Calculated SWE based on work by Sturm and others (2010)
If Tavg > 32°F, snow melt is factored in at: M (in) = a(Tavg - T32), where a is between 0.0766 - 0.1312 in * °F-1 * day-1 (Currently 0.1039) and T32 = 32°F. This method is from Westerstrom (1982) in Kustas and others (1994) and converted to US customary units.
Seasonal Variables DAYS SINCE JULY 11: -13

July 11 is the average snow melt-out day (where snow depth goes down to 0 in) at Paradise
Calculated Variables D0: 2
D1: 1
D2: 2
D3: 2
D4: 1
D5: 2
HSdry: 5.0

These are primarly for the Dry-weather debris flow hazard model, but calculated every day.
HSdry = (([D0 + D1 + D2] * D3) * D4) / D5
See model (right) to figure out how D0 - D5 are calculated.
