As of mid-May, atmospheric conditions across the Atlantic basin show elevated wind shear and stable air masses that continue to suppress tropical cyclogenesis, according to National Hurricane Center monitoring. Sea-surface temperatures remain only marginally supportive in key development regions, and no organized disturbances currently exhibit the low-level circulation or sustained convection required to reach named-storm thresholds before the official June 1 start of the Atlantic hurricane season. Historical climatology indicates pre-season named storms occur in fewer than one in five years, reinforcing the market’s 81.2 percent implied probability for “No.” Traders are closely watching the next series of National Oceanic and Atmospheric Administration model runs and any late-May tropical wave activity for signs of rapid change.
