Peak G 26 Nov: E 45 km/h 2148 and again 2150. These were two freak isolated gusts of this magnitude out of very light background winds, spaced about 2 min apart. 1-min average wind just 11.3 km/h for the former, and a mere 3.2 km/h for the latter. Analog gust register just 30.3 km/h–gusts were too short-lived for the device to fully respond. The truly weird gusts heralded a long Fraser Gap wind event. These offshore winds were triggered by an intense 970 hPa (28.64" Hg) extratropical cyclone that deepened 48 hPa (1.42" Hg) in 24-h, among the highest on record, before landing in extreme northwest California while headed on a southeasterly track. The low-pressure centre nearly passed right over Crescent City: This station reported a phenomenal 51.5 hPa (1.52" Hg) pressure fall in the 24-h ending 1900 26 Nov, one of the largest 24-h pressure changes on record for any station between San Diego and Port Hardy. |

A +SN band moved trough the region, dumping upwards of 12" (30 cm) in a short period of time at some locations. This is a major snowstorm, largest during January in many, many years. Temperatures have also been unusually cold for SN in this region, approaching -10°C (14°F) at times. SN consistency has been low liquid-water content ("dry")–powdery, more typical of interior regions. Recirculating pond frozen solid. The +SN hit at a critical time near the morning commute: School District 43, Douglas College, Coquitlam College, SFU, UBC and UFV all closed. People urged by officials to simply stay home today.

Continuous -RA to +RA past 24-h, ending recently. Major atmospheric river (AR) event, second in a row to occur at month's end (see 01 Jan 2020 entry). RA 5.17" (131.3 mm) from 1700 30 Jan to 0600 01 Feb (37 h)–of this, only 0.35" (8.9 mm) occurred after midnight 01 Feb. RA extremes: Max 15-min 0.10" 1500, 1-h 0.35" 1545, 3-h 0.73" 2030, 6-h 1.36" 2015, 24-h 3.97" 0015. The 24-h total is the all-time high in a period of record going back to 30 Jan 2017, and the 6-h and 1-h are the 7th highest, though the 1-h position is a tie with four other events. Some urban lowland flooding occurred, including ponding of water on roadways, water erupting from storm drains and thick sheets of water pouring down hillside roads. Local streams very high. AR brought a decent mT air intrusion with high Ta 11.2°C 1830 31 Jan and a Td to match, sourced from the vicinity of Hawaii, making this event a classic "Pineapple Express". Total January 2020 precipitation: 21.14" (537.0 mm), wettest going back to Jan 2018 and indeed the all-time highest monthly total for any month going back to February 2017. Considering precipitation records at nearby reservoirs such as Coquitlam, Jan 2020 was likely the wettest in 60 years. Greatest 24-h PCPN 3.95" (100.3 mm) for the period ending 0000 on 31 Jan. The monthly liquid total includes 20.8" (52.9 cm) of snowfall, the highest Jan total on record.

Latest in season SN has been recorded at this site, though not entirely unusual climatologically for the region.
