higher excesses in northern Alabama, including Birmingham (256 mm) and
Huntsville (131 mm) [WET - Up to 7 weeks].
3. East-Central South America:
RAINFALL ABATES, BUT SHORT-TERM MOISTURE EXCESSES PREVAIL
Scattered moderate showers (25 to 100 mm) were limited to southern Santa
Fe and northern Buenos Aires provinces of east-central Argentina while
little or no precipitation was reported elsewhere. Short-term (8-week)
moisture surpluses remained as high as 175 mm in central Uruguay and 285
mm in east-central Argentina [WET - Up to 7 weeks].
4. Western Europe:
STORMS BRING HEAVY RAIN
Thunderstorms swept across western Europe bringing moderate to heavy rains
(20 to 125 mm) to the British Isles, France, and the northern Iberian Peninsula.
Since the beginning of March, moisture excesses of 50 to 250 mm have accumulated
across the region [WET - Up to 6 weeks].
5. Northern Europe:
WETNESS CONTINUES
Wet conditions (15 to 40 mm) again prevailed across northern Scandinavia
and northwestern Russia southward into Belarus. During the past 8 weeks,
100 to 340 mm of precipitation has fallen on the region, which are short-term
departures of 50 to 110 mm [WET - Up to 8 weeks].
6. Central Europe:
WETNESS REMAINS
Showers of 15 to 40 mm kept parts of Hungary, northern Yugoslavia and northwestern
Romania wet. Since the start of March, up to 160 mm of precipitation were
reported, yielding surpluses of up to 60 mm [WET - Up to 14 weeks].
7. Europe and Asia:
EXTENSIVE WARM ANOMALY DEVELOPS
Temperatures averaged 3°C to 10°C above normal across eastern Europe
and most of Asia while weekly departures of +2°C to +6°C
prevailed across northern and southeastern Europe. The mercury soared above
30°C as far north as northwestern Kazakhstan and adjacent parts of
Russia while readings climbed above 20°C as far north as 63°N in
northeastern European Russia. Lows failed to reach freezing during the
week as far north as the Baltic States and extreme southern Scandinavia
(about 60°N) [WARM - Up to 4 weeks].
8. Western Africa:
HIGH TEMPERATURES PERSIST
Temperatures were 1°C to 5°C above normal, and highs soared above
40°C across much of the region, reaching 44°C in Senegal and Mauritania
[WARM - Up to 9 weeks].
9. Southeastern Africa:
WET ANOMALY ENDS, BUT SHORT-TERM MOISTURE SURPLUSES REMAIN
Little or no rain again last week signaled the end of prolonged wetness
across the region; however, 8-week precipitation departures ranged from
+50 to +220 mm [WET - Ended at 25 weeks].
10. East-Central Africa:
MORE VERY DRY WEATHER
Little or no rain fell on Ethiopia and Kenya, except for isolated showers
(50 to 200 mm) in extreme western Kenya. Although as much as 230 mm fell
on the region during the last 8 weeks, moisture deficits ranged from 50
to 315 mm [DRY - Up to 14 weeks].
11. Southwestern Asia:
LITTLE OR NO RAIN REPORTED
Except for isolated showers (up to 50 mm) in northern Oman, eastern Syria,
and southeastern Turkey, scanty precipitation (less than 25 mm) prevailed
across the region. Short-term (March 5 - April 29) moisture deficits reached
170 mm in northwestern Syria, 135 mm in Lebanon, and 110 mm in northern
Iran [DRY - Up to 10 weeks].
12. East-Central China:
DRYNESS PERSISTS
Little or no rain again fell over east central China from northern Sichuan
and southern Gansu Provinces eastward to the Yellow Sea. The region has
received less than 150 mm of rain since March 5, allowing mositure deficits
to reach as high as 160 mm [DRY - Up to 10 weeks].
13. Southeastern China :
HEAVY RAINS AGAIN DOUSE REGION
Very heavy rains (50 to 2000 mm) soaked much of southeastern China from
Guangdong northeastward to Zhejiang. During the last 8 weeks, 150 to 600
mm has fallen over a good portion of the area, which are precipitation
excesses of 50 to 300 mm [WET - Up to 6 weeks].
14. Southeastern Asia and the Philippines:
RAINS CONTINUE
Thunderstorms again brought moderate to very heavy rains (25 to 200 mm)
to Thailand, Malaysia, Cambodia, southern Vietnam, and the Philippines.
Since March 5, amounts of 130 to 625 mm have soaked the region, resulting
in moisture surpluses of 60 to 400 mm [WET - Up to 15 weeks].
15. Northern Half of Australia:
ABNORMAL WETNESS SHIFTS EASTWARD
Torrential rains (100 to 500 mm) drenched the northern and eastern Queensland

of northern and eastern Queensland and the northern part of Northern Territory.
Elsewhere, fewer than 25 mm were reported. Between 100 and 700 mm of rain
has fallen on the northern half of Australia during the last 8 weeks, generating
precipitation excesses of up to 340 mm [WET - Up to 15 weeks].
16. Central Australia:
COOL WEATHER RETURNS
Temperatures averaged 3°C to 5°C below normal in northeastern Western
Australia and central Northern Territory while departures of -1°C to

15°C as far south as 20°S [COLD - 2 weeks].
