1. North-Central United States:
WETNESS SHIFTS NORTHWARD
Heavy rains (50 to 200 mm) drenched western and northern Minnesota, southeastern
North Dakota, and most of central, southern, and eastern South Dakota while
10 to 50 mm dampened central and eastern Montana, Wyoming, and the remainders
of the Dakotas. Lesser amounts were reported across Colorado and Nebraska.
Since the beginning of July, parts of Minnesota and the Dakotas have received
150 to 350 mm more rain than normal [WET - 4 to 7 weeks].
2. Eastern and Southern United States:
REMNANTS OF HURRICANE DENNIS MOVE ASHORE, BUT LONG-TERM MOISTURE
DEFICITS PERSIST
After drifting aimlessly off the Outer Banks of North Carolina, a weakening
Hurricane Dennis made landfall and moved northwestward during the Labor
Day holiday weekend. Rough surf disrupted beach vacation plans from Long
Island southward to Georgia and northeastern Florida while heavy rains
caused localized flash flooding, according to media reports [Episodic Event].
Between 100 and 200 mm of rain, fueled by the remnants of Hurricane Dennis,
inundated eastern North Carolina and southeastern Virginia while 50 to
100 mm fell on north-central North Carolina and the Virginia Piedmont.
Only 10 to 25 mm were reported in Maryland and northern Virginia, but heavy
showers continued across the mid-Atlantic into Labor Day. Significant rains
(10 to 50 mm) also fell on eastern Texas and western Louisiana, but little
or none was reported elsewhere. Short-term (July 1 - September 4) moisture
surpluses
reached as high as 167 mm in Elizabeth City, NC, but most of the region
endured moisture deficits of 100 to 200 mm. In addition, long-term dryness
persisted along the Atlantic Seaboard despite the heavy rains from Hurricane
Dennis [DRY - 4 to 24 weeks].
3. East-Central South America:
MODERATE RAINS DAMPEN SOUTHERN BRAZIL, BUT STILL VERY DRY ELSEWHERE
Between 25 and 50 mm of rain brought limited relief to Rio Grande do Sul
state of southern Brazil and the southwestern and eastern sections of Uruguay
while 10 to 25 mm fell on the remainder of Uruguay. Fewer than 10 mm of
rain were reported in Parana and Santa Catarina states of southern Brazil,
the southeastern half of Paraguay, and northeastern Argentina. Since the
beginning of July, moisture shortages of 50 to 200 mm have accumulated
across the region [DRY - 4 to 8 weeks].
4. Western Europe and North-Central Africa:
WARM ANOMALY SHIFTS NORTHWARD
Temperatures were generally within 3°C of normal across France, Spain,
and Algeria while weekly departures exceeded +3°C in Scotland and Ireland.
The mercury reached 30°C across Spain and southern France and readings
exceeded 20°C across the British Isles [WARM - 2 to 5 weeks].
5. Finland:
PRECIPITATION DEFICITS CONTINUE
Little or no precipitation was reported across Finland as unusually dry
conditions persisted. Moisture shortages of 50 to 100 mm developed across
southern Finland since July 1 [DRY - 4 to 9 weeks].
6. Southern Asia and the Middle East:
STILL UNUSUALLY HOT
Temperatures were 5°C to 8°C above normal across central Mongolia
while readings averaged 3°C to 6°C above normal in northern China
and across central and southwestern Asia. Highs soared above 40°C in
northeastern Sudan, Saudi Arabia, Iran, and Afghanistan while readings
exceeded 30°C as far north as northern Kazakhstan and south-central
Siberia (50°N) [WARM - 2 to 14 weeks].
7. Western India:
POSSIBLE EARLY RETREAT OF THE MONSOON
Although precipitation totaled 50 to 200 mm in northern Madyah Pradesh
and along the coast of Maharashtra, most of western India received fewer
than 50 mm of rain during the past week. Since the first of July, precipitation
shortfalls ranged from 100 to 460 mm [DRY - 4 to 7 weeks].
8. Southern China:
HEAVY RAINS CONTINUE AS TROPICAL STORM WENDY MAKES LANDFALL
Late in the week, Tropical Storm Wendy made landfall in eastern Guangdong,
fueling heavy rains, but no significant media reports were received. Torrential
rains (100 to 200 mm) drenched eastern Yunnan, Guangxi, central Guangdong,
southeastern Hubei, northern Jiangxi, northern Fujian, southern Anhui,
and most of Zhejiang. Locally heavier amounts (200 to 500 mm) inundated
northern Jiangxi and southern Zhejiang. The remainder of southern China
experienced 25 to 100 mm of rain. Since the beginning of July, precipitation
totals were 100 to 300 mm above normal, with moisture excesses of 300 to
700 mm at scattered locations [WET - 4 to 10 weeks].
9. Northeastern China:
ABNORMAL DRYNESS PERSISTS
Little or no rain fell on northeastern China from Gansu northeastward through
eastern Nei Mongol, but 25 to 100 mm of precipitation brought limited relief
to extreme northeastern Nei Mongol. In addition, 25 to 100 mm of rain dampened
central Shandong and eastern Henan. Precipitation shortfalls for the period
from July 1 through September 4 ranged from 100 to 335 mm across most of
the region [DRY - 4 to 11 weeks].
10. Australia:
WARM ANOMALY DEVELOPS
Temperatures averaged 6°C to 9°C above normal across western New
South Wales while departures of +3°C to +6°C dominated Queensland,
the remainder of New South Wales Victoria, Tasmania, South Australia, and
southeastern Western Australia. Highs ranged from 30°C to 35°C
across most of South Australia, northwestern New South Wales, western Queensland,
and eastern Western Australia while the mercury climbed above 20°C
elsewhere, except on Tasmania [WARM - 2 weeks].
