Africa Update #27: On the Brink of Catastrophe in the East

Although there is more rain falling in eastern Africa than there has been all season long, some areas still haven't seen a drop. The rains are nearly two months late in a three month wet season. A clear Intertropical Convergence Zone has set itself up in west Africa, a good sign there. In the south the wet season continues to come to a close and is showing no signs of pulling out early. Rains are picking up in the north, including disrupting the conflict in Libya.

Latin America Update #26: Rains Arrive in Central America Highlands

Early season rains pushed into Central America this past week. Flooding remain firmly entrenched in central Colombia. Northeastern South America remained dry, raising concerns after more than a month of poor rainfall. The Amazon River basin was also dry, but here the break is a respite from the heavy rains of the previous weeks. A front provided late season rains to the Rio de la Plata basin, as far north as Paraguay.

Asia Update #25: Drought Devastating Southern China

Southern China is continuing to face one of the worst droughts it has faced in recent history. Elsewhere, rainfall is slightly off in eastern Bangladesh and northeastern India, but not significantly so. In southeast Asia, rains have progressed northward across the mainland. Light rains continue to fall in parts of Central Asia, eastward to Turkey, after the typical end of the season.

Africa Update #25: Improvement in the East, but little Hope

Despite some improved rainfall across the east, there is little reason to think that there will be vast season long improvement. This contrasts with west Africa, where early season rainfall has been more than sufficient. In the south, some isolated flooding remains problematic. There has been very little rainfall in Libya, so weather has been irrelevant in the conflict.

Latin America Update #24: Rains Focused in the Amazon Basin and Northern Andes

Rainfall continues to be focused on northern South America, with southern areas drying out earlier than normal, dashing any remaining hopes of pulling out a reasonable harvest. Preseasonal showers continue to pick up in intensity in Central America and the Caribbean.

Asia Update #24: Slow Start to the Indian Monsoon

There has been a slightly slow start to the Indian monsoon, although it is too early to tell if this will have a significant impact on the season. Southern China remains locked into a long term drought, as excessive rainfall continues to pound southeast Asia.

Latin America Update #23: Rains Pull North

The rains are pulling north faster than usual. That means that Panama was wetter than usual, and Argentina is drier. In between those extremes are Colombia and Venezuela, where the last week brought poor rains, while patches across Peru, Bolivia, Paraguay and Brazil had unusually heavy rains.
