Degree Days above 32°F
(DD32) |
TODAY'S DD32: 35
18-DAY CUMULATIVE DD32: -57
DD32 is calculated as: DD32 = TMAX - 32
18-day Cumulative DD32 is the sum of DD32 for the last 18 days.

| Snow at Paradise |
DEPTH: 0 in
SWE DAY: 194
CALCULATED SNOW DENSITY: 435.18 kg/m3
CALCULATED SWE: 0.00 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.

DAYS SINCE JULY 11: 2
July 11 is the average snow melt-out day (where snow depth goes down to 0 in) at Paradise
|
| Calculated Variables |
D0: 3
D1: 2
D2: 1
D3: 1
D4: 5
D5: 2
HSdry: 15.0
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.
