St. Maarten and St. Martin weather forecasts, radar images, radar loops, and hurricane information
See this helpful information compiled by CNN. Also read these precautions; here's detailed disaster preparation advice. Many maps and satellite images follow on this continuously updated page.
Brief Introduction:
Although this page gives you a number of still radar images and radar loops (below), it no longer -- by design -- directly publishes forecasts. We'll give you two sources of forecasts in a second, but first this warning: if a storm is approaching your area, never rely on any website as your sole source of information. Always heed advisories from local authorities. This website is for informational purposes only.

Current St. Maarten and US-Related Satellite Images
Current Weather Images: All maps are satellite images, updated as frequently as every half hour, courtesy of NOAA unless otherwise noted. If you see no images, the NOAA server is down. IMPORTANT! If you come back in a couple of hours to recheck these images to see where storms are moving (and how fast), when the image loads check the upper left corner. It tells you the date and Greenwich Mean Time (GMT) of the image (time + Zulu, indicating GMT). If the time hasn't changed since you last viewed the image, click your browser's REFRESH button. Then you'll get the new image. (In the name of efficiency, browsers store files -- even ones which update around the clock.) Again, if an image fails to appear here, the weather site is down.

Storms Crossing Africa East to West . . .
During the Cape Verde Season (mid August to mid October), Significant Atlantic Tropical Waves Are Born Here

Tropical Waves Exiting the African Coast
During the "Cape Verde" season from August through mid October, this is where storms threatening SXM usually come from. Waves move east to west just north of the "Intertropical Convergence Zone" (ITCZ). Focus on storms between 10 and 20 degrees north.... Starting in late July, "shearing" winds over the tropical Atlantic begin to diminish, heralding the beginning of the Cape Verde season. Its peak is September. Satellite photos update constantly.
Atlantic Basin Water Vapor Imagery
Why is this significant? Storms encountering dry air tend to lose strength; those traveling in moist air can maintain or gain strength, depending on other conditions.
