According to the database, there were no geologic events (floods, debris flows, outburst floods, etc) on this day.

THIS DAY'S DEBRIS FLOW HAZARD CLASS:
L
LOW

MODEL USED FOR HAZARD CLASS DETERMINATION:

WET

MODEL VARIABLES AND OUTPUT:
Temperature at Paradise MAXIMUM TEMPERATURE (Tmax): 0.00°F
MINIMUM TEMPERATURE (Tmin): 0.00°F
AVERAGE TEMPERATURE (Tavg): 0.00°F

MAXIMUM TEMPERATURE PERCENTILE (Tmax percentile): 0.000
Maximum Percentile on this day is based on 17 years of historic (1917-2017) records:

DEBRIS FLOW HAZARD MODEL:


Click to zoom in
Degree Days above 32°F
(DD32)
TODAY'S DD32: -32
18-DAY CUMULATIVE DD32: -73

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): 0.85 in
DAY 4-15 (P15): 4.62 in
18-DAY TOTAL (P18): 5.47 in

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

PRECIP THRESHOLD B (PB) EXCEEDED: False
P3 > (-0.67 * P15 + 4.5)
Snow at Paradise DEPTH: 146 in
SWE DAY: 81
CALCULATED SNOW DENSITY: 425.37 kg/m3
CALCULATED SWE: 62.10 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: -111

July 11 is the average snow melt-out day (where snow depth goes down to 0 in) at Paradise
Calculated Variables D0: 1
D1: 1
D2: 1
D3: 3
D4: 5
D5: 2
HSdry: 22.5

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.
