Discussion: Extremely dry weather was observed the last week of April across South-central to Coastal Brazil. The 10-day outlook maintains the dryness with high temperatures consistently in the 32-35C range. The dry pattern widens during the period.

Week-2 Valid May 12-18, 2024: Worsening Brazil drought.

Discussion: The anomalous heat and dryness in Brazil will continue as feedback between widening drought and sustaining high pressure aloft strengthens.

Week-4 Valid May 26-June 1, 2024: Dryness in Brazil shifts slightly westward.
