This system could separate from its front and acquire some subtropical or tropical characteristics on Saturday or early Sunday while it moves east-southeastward at 10 to 15 mph toward Portugal and northwestern Spain. For more information, see High Seas Forecasts issued by Meteo France. * Formation chance through 48 hours...low...20 percent. * Formation chance through 7 days...low...20 percent. Central Subtropical Atlantic: A weak area of low pressure located over the central subtropical Atlantic a few hundred miles east-southeast of Bermuda is producing a concentrated area of showers and thunderstorms southeast of its center. Surface pressures in the area are relatively high, therefore development of this system, if any, is expected to be slow to occur while it drifts west-southwestward through Sunday and then turns northward early next week. * Formation chance through 48 hours...low...10 percent. * Formation chance through 7 days...low...20 percent. && High Seas Forecasts issued by Meteo France can be found under WMO header FQNT50 LFPW and on the web at https://tgftp.nws.noaa.gov/data/raw/fq/fqnt50.lfpw..txt
