DROUGHT WORSENS ACROSS THE NORTHERN MARSHALL ISLANDS
The synoptic pattern the last few weeks has been characterized by a featureless, moderate northeast trade-wind flow across the Marshall Islands. The inter-tropical convergence zone has been largely non-existent. These conditions have led to dry conditions for atolls of the RMI near 10N with minimal shower activity farther south across the central and southern Marshall Islands.
La Nina continues based on large-scale oceanic and atmospheric conditions. A series of westerly wind bursts in December 2021 should chew into the La Nina signal the next several months, with ENSO neutral possibly establishing by late spring. Overall expectations are for drought to worsen across the northern Marshall Islands for the next month or so before showers begin to pick up. This largely follows climatology and trends in seasonal climate models.
