Fewer than 25 mm of precipitation were observed across the remainder of the region. Short-term (8-week) moisture shortages of 100 to 200 mm dominated the central states from Louisiana and southeastern Texas northward through northeastern Missouri and west-central Illinois while short-term deficits of 50 to 100 mm prevailed elsewhere [DRY - Up to 12 weeks].

2. Central and Eastern United States and Southeastern Canada:

STRONG WARM ANOMALY SHIFTS EASTWARD Temperatures averaged 6°C to 10°C above normal across southeastern Canada and the northeastern United States, with the highest departures in the eastern Great Lakes region while weekly departures ranged from +3°C to +6°C elsewhere. The mercury soared above 20°C as far north as northwestern New York and the northern portions of Vermont and New Hampshire, and temperatures remained above freezing along the southern shore of Lake Ontario [WARM - Up to 5 weeks].

3. Northern Argentina:

SHORT-TERM MOISTURE SURPLUSES REMAIN Fewer than 25 mm of rain fell on the region last week, except for scattered heavier amounts (25 to 100 mm) in Mendoza, La Rioja, Cordoba, and Tucuman. Despite the relatively dry week, short-term moisture surpluses of 100 to 500 mm prevailed across northern Argentina [WET - Up to 8 weeks].

4. Uruguay and Adjacent Parts of Brazil and Argentina:

LIGHT TO MODERATE RAINS REPORTED The first significant precipitation across Uruguay in 6 weeks yielded 10 to 50 mm of rain, but fewer than 25 mm fell on adjacent sections of Argentina and Brazil.

Temperature dipped as low as -19°C at Poprad, Slovakia (49°N) and -24°C at Voroshilovgrag, Ukraine (48°N) [COLD - Up to 3 weeks].

6. Southeastern Asia:

DRY WEATHER PROVIDES RELIEF Little or no rain fell across most of the region with moderate to heavy rains (25 to 60 mm) limited to the central Vietnamese coast. Despite the dry week, 300 to 2050 mm of precipitation (140 to 930 mm more than normal) has drenched Vietnam during the last 8 weeks while 300 to 800 mm has accumulated over much of the reminder of the area during this same period, yielding moisture surpluses of 150 to 280 mm [WET - Up to 8 weeks].

7. Northeastern Australia:

TORRENTIAL RAINS LASH COASTAL QUEENSLAND Heavy showers dropped 100 to 200 mm of rain on the eastern coast of northern Queensland, with a couple of locations receiving more than 200 mm, while the remainder of the region received 25 to 100 mm. Most of northern and eastern Queensland has received 100 to 500 mm of rain since the beginning of October, resulting in precipitation excesses of 100 to 375 mm [WET - Up to 8 weeks].

8. Central and Eastern Australia:

In addition, the mercury remained below 20°C in the southern, eastern, and western portions of Tasmania [COLD - Up to 5 weeks].

9. Southeastern Australia:

During the past 8 weeks , moisture shortages of 100 to 200 mm accumulated along the eastern coast of Tasmania while short-term deficits of 50 to 200 mm were reported along the eastern coast of New South Wales. [DRY - Up to 11 weeks].
