Météo France Antilles-Guyana said this Thursday, July 10, cyclonic monitoring will remain fully ensured during this cyclonic season in the Atlantic basin. A response to the announcements of the Americans to the suspension of sharing some of their satellite data.
Initially scheduled for June 30, the cessation of images sharing of certain data from several American satellites will finally be effective on July 31. Officially for security reasons according to American services, this withdrawal had caused some questions within Météo France on the quality and precision of the monitoring of cyclonic activity on the Atlantic basin. After recognizing that the cessation of these transmissions could “have” temporarily concrete and regrettable consequences “, A shade is therefore brought 3 days later by saying that” many other data sources Were available to feed these forecasts.
Météo France also insists that the data produced by American geostationary satellites ” are not affected by the recent announcement “, And ensures having European Satellites Meteosat as well as its own network of meteorological radars.
US data from scrolling satellites equipped with sensors called ” Passive microwave imaging “, Have the capacity to detect cloudy structures particularly interesting for the positioning and monitoring of cyclonic phenomena day and night. They also offer reliable forecasts over the days following the first observations, but however only constitute a tiny part of the many data ingested. They would represent ” less than 1% “Satellite observation data that fueling the French digital” arpege “model reassures Météo France.
For this 2025 cyclonic season, 13 to 19 storms are expected of which 6 to 10 could become hurricanes and 3 to 5 could reach the stage of major hurricanes.
