1. Southern Alaska and Adjacent Parts of Canada:
RELATIVELY MILD CONDITIONS DOMINATE
Large positive temperature departures (+6°C to +9°C) covered eastern
Alaska and northwestern Canada, with highs at a few locations approaching

week [WET - Ending at 10 weeks].
3. Southwestern British Columbia and Northwestern Washington:
MODERATE TO HEAVY RAINS BRING RELIEF
Torrential rains (100 to 500 mm) soaked Vancouver Island and orographically-favored
areas in British Columbia and northwestern Washington while 50 to 100 mm
were reported elsewhere. During the last 8 weeks, fewer than 300 mm of
precipitation accumulated, resulting in short-term moisture deficits as
high as 320 mm [DRY - Ending at 8 weeks].
4. Ontario:
STILL UNUSUALLY COLD
Bitterly cold weather, characterized by temperatures averaging 6°C
to 10°C below normal, dominated northern and central Ontario while
temperatures were 2°C to 6°C below normal elsewhere. The mercury
managed to reach the freezing mark across southern Ontario, but readings
fell below -20°C across most of the province [COLD - Up to 8 weeks].
5. Eastern United States:
SEVERE WEATHER BATTERS EAST
Strong winds and numerous tornadoes raked the eastern United States during
the past week, resulting in loss of life and considerable property damage
according to the media. Moderate to heavy rains (50 to 100 mm, with locally
higher amounts to 200 mm) soaked the area, providing additional relief
from long-term dryness [Episodic Events].
6. East-Central South America:
RAINFALL ABATES
Heavy rains (50 to 200 mm) were restricted to the extreme northern and
southern fringes of the region while totals of 10 to 50 mm prevailed across
the remainder. During the last 13 weeks, precipitation totaled 100 to 500
mm, with locally higher amounts reaching 1100 mm. These accumulations resulted
in moisture excesses of 100 to 500 mm, with a few higher surpluses approaching
800 mm [WET - Up to 12 weeks].
7. Western Europe:
MORE WET WEATHER
Moderate to heavy precipitation (50 to 200 mm) inundated south-central
England and much of the Alps while lesser amounts (10 to 50 mm) were observed
elsewhere. Between August 18 and November 16, the region received 100 to
500 mm of precipitation, with locally heavier amounts of up to 1100 mm
in the Alps. The 13-week moisture surpluses ranged from 50 to 300 mm across
most of the region, and exceeded 550 mm in some higher elevation Alpine
locations [WET - Up to 11 weeks].
8. Scandinavia:
COLD AIR REMAINS ENTRENCHED
A large variation in temperature departures (-2°C to -8°C) prevailed
across Scandinavia as cold air continued to dominate the region. Highs
above freezing were restricted to southern portions of Scandinavia with
a marine influence while the mercury plummeted below -20°C as far south
as the southern portions of Norway, Sweden, and Finland [COLD - Up to 7
weeks].
9. Sweden and Finland:
PRECIPITATION DEFICITS PERSIST
Little or no precipitation fell on Sweden and Finland during the past week.
During the last 13 weeks, fewer than 120 mm of precipitation accumulated
in the two countries, yielding 91-day moisture deficits of 50 to 200 mm
[DRY - Up to 11 weeks].
10. Eastern European Russia:
LIGHT TO MODERATE PRECIPITATION CONTINUES
Between 10 and 50 mm of precipitation fell on the region during the past
week. Precipitation amounts during the last 13 weeks ranged from 150 to
400 mm, allowing moisture surpluses of 50 to 250 mm to accumulate [WET
- Up to 11 weeks].
11. East-Central Africa:
SHORT-TERM MOISTURE SURPLUSES REMAIN
Moderate to heavy rains (50 to 200 mm) fell on southwestern Kenya, but
generally less than 50 mm were reported elsewhere. During the last 4 weeks,
precipitation totaled 100 to 500 mm, which is among the highest 10% of
the climatological distribution [WET - Up to 6 weeks].
12. Zimbabwe and Southern Mozambique:
PRECIPITATION ABATES
Little or no rain fell on the region, except for isolated totals of 50
to 100 mm in southeastern Zimbabwe. Between 70 and 140 mm of rain accumulated
during the last 4 weeks, placing totals among the highest 10% of the climatological
distribution [WET - Up to 6 weeks].
13. China and Mongolia:
ABOVE-NORMAL TEMPERATURES REPORTED
Temperatures averaged 2°C to 5°C above-normal during the past week,
with highs above the freezing mark throughout the region. The mercury soared
above 30°C in southern China. Lows remained above freezing across the
southern half of the region, but dropped below -20°C at some of the
higher elevations [WARM - Up to 3 weeks].
14. Korea and Japan:
COLD AIR CONTINUES EASTWARD TREK
Temperatures were 2°C to 4°C below normal across Korea and Japan,
with the largest negative departures reported in North Korea and on northern
Honshu Island of Japan. Subfreezing lows penetrated as far south as central
South Korea and central Honshu [COLD - Up to 5 weeks].
15. Southeastern China:
WET ANOMALY DEVELOPS
Torrential rains (100 to 200 mm) drenched eastern Hubei, northern Jiangxi,
southern Anhui, and most of Zhejiang while moderate to heavy precipitation
(25 to 100 mm) fell on the remainder of the region. During the last 28
days, precipitation totals of 80 to 270 mm, were among the highest 10%
of the climatological distribution [WET - Up to 5 weeks].
16. South-Central China:
ABNORMALLY DRY CONDITIONS EVOLVE

17. Eastern Australia:
STILL VERY DRY
Light to moderate rain showers (10 to 100 mm) were restricted to coastal
regions of southeastern Queensland and northeastern New South Wales. The
remainder of eastern Australia received little or no rain. Fewer than 100
mm of rain has accumulated during the past 8 weeks, leading to precipitation
shortfalls of 50 to 200 mm [DRY - Up to 8 weeks].
18. Australia:
MORE HIGH TEMPERATURES
Weekly temperature departures of +2°C to +6°C dominated central
and southern Australia, with highs exceeding 40°C across much of the
interior [WARM - Up to 5 weeks].
