and the southern and central portions of Arizona [WARM - Up to 10 weeks].
2. Central United States:
UNUSUALLY DRY CONDITIONS PERSIST

the region. Since late July, little or no precipitation has fallen on much
of western and central Texas and much of Oklahoma but up to 100 mm fell
on eastern portions of Texas. Meanwhile, between 25 and 100 mm of rain
accumulated across the central and northern Great Plains. Short-term precipitation
shortfalls ranged from 100 to 150 mm across the central and southern Great
Plains from eastern Kansas and western Texas southeastward to the Gulf
Coast [DRY - Up to 24 weeks].
3. Southern South America:

but the mercury managed to reach 20°C across most of northern and central
Argentina [COLD - Up to 6 weeks].
4. Central Chile:
WET WEATHER DEVELOPS
Pacific storms delivered 50 to 100 mm of rain this past week on top of
the 50 to 200 mm received the week before. During the last 8 weeks, 170
to 490 mm of precipitation has fallen on the region, yielding moisture
excesses of 50 to 240 mm [WET - Up to 6 weeks].
5. Brazil:
FAVORABLY DRY CONDITIONS REPORTED
Fewer than 30 mm of rain fell on southern and central Brazil north of Parana
while totals of 50 to 100 mm soaked Santa Catarina. Across the region,

- Up to 6 weeks].
6. Uruguay and Southern Brazil:
HEAVY PRECIPITATION DRENCHES AREA
Torrential rains (100 to 200 mm) inundated the southern half of Rio Grande
do Sul province of Brazil and much of northern and eastern Uruguay while
25 to 100 mm of precipitation fell on the remainder of Uruguay. During

Temperature departures of +2°C to +5°C covered a large portion
of central Asia extending from Turkmenistan eastward across southeastern
