1. Northwestern United States and Southwestern British Columbia:
MODERATE PRECIPITATION REPORTED
Pacific storms delivered 20 to 80 mm of precipitation to the Pacific Coast
from northwestern California northward to west-central British Columbia,
with locally heavy amounts (80 to 150 mm) falling on northwestern Washington
and Vancouver Island. Since the beginning of February, between 200
and 400 mm of precipitation has fallen on the region, resulting in moisture
excesses as high as 300 mm. Some locations reported exceptional amounts,
including the 1002 mm at Quillayute, WA and the 1093 mm at Estevan Point,
BC which were 424 mm and 539 mm above normal, respectively [WET - Ending
at 7 to 15 weeks].
2. North-Central United States and Western Great Lakes:
MORE DRY WEATHER
Little or no precipitation fell on the region last week, except for 10
to 20 mm in central Minnesota. Between 20 and 70 mm of precipitation has
fallen on the region since the beginning of February, resulting in moisture
deficits of up to 60 mm [DRY - 4 to 7 weeks].
3. Southeastern United States:
VERY DRY CONDITIONS PREVAIL
Generally less than 10 mm of rain fell on Florida, southern Georgia, and
southeastern Alabama as abnormally dry weather continued. During February
and the first 27 days of March, precipitation shortfalls reached as high
as 225 mm [DRY - 5 to 9 weeks].
4. East-Central South America:
STILL VERY WARM
Temperatures were generally 1°C to 4°C above normal across the
region, but weekly departures reached +5°C in northeastern Argentina
and +7°C in southern Brazil. The mercury climbed above 30°C as
far south as Laboulaye, Argentina (34°S) [WARM - 2 to 7 weeks].
5. Western Europe:
WARM ANOMALY ABATES
Temperatures averaged near normal across western France and northeastern
Spain, and 1°C to 3°C above normal in the British Isles [WARM -
Ending at 2 to 4 weeks].
6. Western Sahel Region:
ABOVE-NORMAL TEMPERATURES PERSIST
Weekly departures of +3°C to +9°C dominated southern Mali, with
highs reaching 45°C at Kayes (14°N). Elsewhere, temperatures were
1°C to 3°C above normal. The mercury climbed above 40°C across
eastern Senegal, extreme southern Mauritania, Burkina Faso, and most of
Mali, but remained below 40°C in Guinea and the northern sections of
Côte D'Ivoire, Ghana, Togo, and Benin [WARM - 2 to 4 weeks].
7. Southern Africa:
HEAT WAVE DIMINISHES
Temperatures were within 3°C of normal this past week, but highs exceeded
30°C at many locations [WARM - 3 to 7 weeks].
8. Northern and Central Asia:
COLD ANOMALY SPREADS NORTHWARD
Abnormally cold air, with temperatures averaging 4°C to 11°C below
normal, covered a large land expanse including most of Siberia, Kazakhstan,
Kyrgyzstan, Mongolia, and extreme northern China. Temperatures dropped
to as low as -50°C at Ojmjakon, Russia (63°N) [COLD - 2 to 4 weeks].
9. Southeastern Asia:
COLD AIR INVADES CHINA, BUT STILL VERY WARM ELSEWHERE
Cold Arctic air overspread most of China, bringing the warm weather to
an abrupt end. Meanwhile, temperatures averaged 1°C to 4°C above
normal across the Indochina Peninsula, Taiwan, and Japan. Highs were generally
above 30°C in the Tropics, with isolated readings above 40°C reported
in northern Thailand [WARM - Ending at 2 to 10 weeks].
10. South-Central China:
DRYNESS CONTINUES
Light to moderate rain (5 to 35 mm) dampened Guizhou while light
scattered rain (less than 10 mm) fell on northern Vietnam and
Guangxi and eastern Yunnan provinces of southern China. Since the start
of February, the region has received less than 100 mm, allowing deficits
of 55 to 160 mm to accumulate [DRY - 4 to 12 weeks].
11. East-Central China and Southern Japan:
MOISTURE ANOMALY DEVELOPS
Thunderstorms brought moderate to heavy rain (40 to 125 mm) to most of
Zhejiang, eastern Anhui, and southern Jiangsu in China, and Kyushu and
the Ryukyu Islands in Japan. Since the beginning of February, as much as
285 mm of rain have fallen in east central China, 330 mm in the Kyushu,
and 890 mm in the Ryukyu Islands, yielding short-term moisture surpluses
of 55 to 465 mm [WET - 4 to 6 weeks].
12. Northern Borneo and the Philippines:
PRECIPITATION SURPLUSES REMAIN
Generally less than 50 mm of rain was reported last week, but scattered
heavy thunderstorms dumped 100 to 400 mm on scattered portions of the eastern
Philippines. Between 100 and 1500 mm of rain has fallen on northern Borneo
Island and the Philippines during February 1 through March 27, resulting
in short-term precipitation surpluses of 100 to 650 mm [WET 4 to 10 weeks].
13. Western Australia:
TROPICAL CYCLONE VANCE BRINGS HEAVY RAIN, STRONG WINDS, AND
COOL WEATHER
Tropical Cyclone Vance achieved category 4 status with sustained winds
exceeding 231 kph prior to making landfall in Western Australia. The media
indicated that significant damage occurred at some locations. The storm
and its remnants pushed into the interior of Australia, fueling heavy rains
(100 to locally 350 mm) across west-central and northwestern Western Australia;
moderate rains (20 to 100 mm) extended southeastward through the state
to the southern coast. Temperatures averaged as much as 4°C below normal
across central and southern Western Australia as a result of increased
cloudiness [Episodic Events].
14. Northeastern Australia:
HEAT WAVE CONTINUES
Temperatures averaged 3°C to 7° above normal across northeastern
South Australia, southeastern Northern Territory, southwestern Queensland,
and northwestern New South Wales. The mercury soared above 30°C throughout
the region and reached 40°C at Oodnadatta (26°S) [WARM - 2 to 5
weeks].
