WEATHER BULLETIN FOR SHIPS
SURINAME COAST & THE GUIANAS | 05N–15N / 45W–60W
🚨 PART I: STORM WARNING
NO STORM WARNING. No storm warning is currently active for the forecast area.
🌐 PART II: SYNOPTIC OVERVIEW — Situation 1200UTC, October 01, 2026
The Intertropical Convergence Zone (ITCZ) axis is analyzed along a mean position stretching from 06°N45°W to 07°N52°W and extending toward 06°N58°W. Low-level moisture convergence along the ITCZ remains high. An active tropical wave embedded in the deep easterly flow has its axis analyzed near 52°W–54°W, moving westward at 12–15 kt. Enhanced low-level vorticity and moisture advection associated with this wave interact directly with the ITCZ band, generating enhanced deep convection, moderate-to-heavy showers, and squall lines across the central and western offshore sectors.
🌧 Saharan Dust: No significant Saharan Air Layer intrusion was identified.
