Looking at the tropics tonight reveals some new developments including a new tropical storm in the Atlantic Basin. Tropical Storm Frances is the sixth named tropical system of the Atlantic Hurricane Season. This brings us up to 6 named storms, 3 hurricanes, and 2 major hurricanes so far this season. Tropical Storm Frances is a minimal tropical storm at 5 PM EDT with maximum sustained winds of near 40 mph with higher gusts. Frances is expected to gradually strengthen over the next couple of days and is forecast to become a hurricane in the next 48 hours or so. Tropical Storm Frances is centered near latitude 11.6 north, longitude 40.5 west or about 1420 miles east of the Lesser Antillies. Movement is towards the west at near 17 mph and this motion is expected to continue during the next 24 hours. The key to this forecast is how far north will this system reach. If this system tracks further northwestward, it will likely run into higher shear, hence possibly a minimal hurricane strength. However a track further south could result in further strengthening south of a ridge axis and possibly a stronger hurricane of category 2-3 or higher. No immediate threat to land is anticipated with this system and it's over a week away from coming anywhere close to the United States if it even makes it this far west.
Meanwhile another system of note off the Florida/Georgia coast with persistent showers and thunderstorms. However pressures at the surface have gone up today and pressure are high to begin with. As a result, immediate strengthening to a tropical cyclone doesn't look likely. However over the next day or two, we could see conditions favor further slow strengthening. Definitely something to keep an eye on.
Meanwhile the west Pac is quite busy with two typhoons. Aere hasn 75 mph winds and is impacting Mainland China at this time after slamming Taiwan with several feet of rainfall. Finally the big system of all, Supertyphoon Chaba has maximum sustained winds of 165 mph with higher gusts. Chaba is positioned near latitude 22.7N, longitude 136.6W. Movement is north-northwest at near 9 mph. The track would take this sytem towards southern Japan as a category 3, possibly stronger. A very devastating situation potentially for southern Japan over the next 4-5 days.
