1. The downgrade of Sandy to a tropical storm was a mistake by NHC in my opinion. The pressure is falling, and Sandy will come in with the impacts like a hurricane is what I think is happening now. Sandy is going through the change from a tropical system to an extra-tropical system, so from a tropical sense, yes, Sandy is not really a hurricane, but from a meteorological sense, Sandy is getting bigger and the pressure is expected to fall to sub 950 mb. At that pressure, winds will be over hurricane force. The two images below show the GFS wind speeds in knots.
2. Sandy will be a dangerous storm coming in with a storm surge that will hit Long Island, the south coast of New England and even into New York City. The Jersey beaches to the Maryland beaches will be flooded and in some areas, the ocean is going into the streets.
Erika will have many issues this weekend includng tracking over the islands with big mountains.
Erika will track into the Bahamas and may intensify early next week. Track could bring it close to the U.S.
Erika's path and intensity over the next five days is the concern of the day.
We continue to watch the tropics as now we have a new storm.
The weather this week across the country will be calm, but we still have Danny out there lurking later this week.
Active day of severe weather across the Upper Midwest Satruday afternoon.
