1. North-Central United States and South-Central Canada:

COLD AIR DOMINATES REGION
A succession of cold Canadian air masses resulted in weekly departures of -1°C to -4°C across the north-central United States while departures approached -6°C in southern Manitoba. Subfreezing temperatures pushed as far south as southern Kansas, and the mercury dropped below -10°C in northeastern Montana and northwestern South Dakota [COLD - Up to 4 weeks].

2. Central and Southern United States:

RAINS BRING RELIEF, BUT STILL VERY DRY IN TEXAS
Abundant rains (25 to 100 mm) provided welcome relief to much of the Ohio Valley and the South from Kentucky southward to the Gulf Coast. Farther west, little or no rain fell on Texas as very dry weather continued. Moisture deficits since August 15 ranged from 100 to 200 mm in southeastern Ohio, from northern Mississippi eastward to northwestern Georgia, along the Gulf Coast, and across most of Texas [DRY - Up to 14 weeks].

3. Eastern United States:

A RELATIVELY DRY WEEK
Little or no rain fell on the central and eastern portions of the Carolinas and southeastern Virginia, allowing disaster recovery efforts to continue in flooded regions. Fewer than 30 mm of rain were reported along the Appalachians, but 25 to 50 mm dampened parts of the mid-Atlantic and southern New England. Precipitation excesses since August 15 ranged from 100 to 300 mm in most areas, and reaching as high as 477 mm at Raleigh-Durham, NC [WET - Up to 8 weeks].

4. Mexico:

HEAVY RAINS CAUSE SEVERE FLOODING
Torrential rains (up to 200 mm reported -- but reliable data are lacking), fueled by the remnants of a tropical depression, inundated southern and east-central Mexico. According to the media, flooding caused loss of life and forced thousands from their homes [Episodic Event].

5. East-Central South America:

MORE VERY DRY WEATHER
Moderate showers brought 25 to 50 mm of rain to Rio Grande do Sul in extreme southern Brazil, but fewer than 30 mm fell elsewhere. Since the middle of August, moisture deficits of 100 to 250 mm accumulated across southern and eastern Paraguay, western and central Uruguay, extreme northeastern Argentina, and southern Brazil from Parana southward to northern Rio Grande do Sul while short-term departures ranged from 50 to 100 mm elsewhere [DRY - Up to 13 weeks].

6. Western and Northern Europe:

FAVORABLY DRY WEATHER REPORTED
Most of the region received less than 25 mm of rain, providing some relief from the recent weeks of wet weather. Unfortunately, moderate to heavy rains (25 to 100 mm) fell on the Alps, the western portions of the Benelux Countries, much of southern Scandinavia, and exposed locations of Scotland, Wales, and England. Short-term (August 15 - October 9) moisture surpluses exceeded 330 mm in Switzerland, and reached 150 mm in parts of northern Portugal, western and northern France, and southwestern Belgium [WET - Up to 8 weeks].

7. Western Sahel:

VERY WET WEATHER CONTINUES
Between 50 and 100 mm of rain soaked eastern Burkina Faso and the northern portions of Togo, Benin, and Nigeria, with locally heavier rains (up to 200 mm) in Benin. During the past 8 weeks, 200 to 620 mm of rain has fallen on the region, yielding short-term surpluses of 100 to 300 mm [WET - Up to 7 weeks].

8. Eastern Europe and Western Asia:

WARM ANOMALY SHIFTS EASTWARD
Temperatures were 6°C to 10°C above normal across western Siberia, eastern European Russia, and northern Kazakhstan while weekly departures of +3°C to +6°C prevailed across western European Russia, Turkey, the Middle East, and the remainder of Kazakhstan. Highs soared up to 35°C in parts of the Ukraine and southern European Russia, and the mercury topped 36°C in Syria. [WARM - Up to 3 weeks].

9. Northeastern China:

DRYNESS PERSISTS
Little or no rain fell on Manchuria as unusually dry conditions persisted. Most locations received fewer than 100 mm since the middle of August, but moisture deficits were less than 100 mm as precipitation normals began their seasonal decline [DRY - Up to 7 weeks].

10. Southeastern China and Northern Philippines:

TYPHOON DAN BRINGS HEAVY RAINS
Torrential rains (200 to 500 mm), fueled by Typhoon Dan, inundated the northern Philippines and southern Taiwan [Episodic Event]. Just after passing the Philippines, the typhoon made an abrupt turn northward to southeastern China, bringing strong winds and moderate to heavy rains (50 to 200 mm, with locally higher amounts) before making landfall and dissipating in Fujian province. Since August 15, more than 200 mm of rain has drenched southeastern China, with some locations receiving over 500 mm, resulting in precipitation excesses of 100 to 250 mm at most locations and reaching as high as 360 mm in Guangzhou [WET - Up to 15 weeks].

11. Southeastern Australia:

UNUSUALLY WARM CONDITIONS PREVAIL
Temperatures averaged 3°C to 6°C above normal across much of South Australia, southern Queensland, New South Wales, Victoria, and Tasmania, with highs exceeding 30°C across the interior regions, and reaching 40°C in northeastern South Australia [WARM - Up to 3 weeks].

12. Victoria and Tasmania:

STILL VERY DRY
Little or no rain fell on Tasmania last week while most of Victoria received fewer than 30 mm of precipitation. A notable exception was the 25 to 50 mm of rain reported in south-central Victoria, which provided limited relief. Above normal temperatures (see item 11 above) exacerbated the dryness in extreme southeastern Australia. Despite the prolonged dryness, precipitation deficits since August 15 were generally less than 100 mm [DRY - Up to 8 weeks].
