Here's a look at AL94 in imagery from GOES-19. The system is expected to develop into a tropical depression during the weekend. While there continues to be uncertainty, people along parts of the southeastern US coast should follow this system closely. weather.us/satellite/74... TT

Rainfall from AL94 can be seen today in radar images from Puerto Rico. This tropical wave could become a tropical depression near Bahamas in a few days. There is still quite a bit of uncertainty but Bahamas and SE US should keep an eye on this system. weather.us/radar-us/pue... TT

Here's a look at dew points across the CONUS this noontime amid a risk of severe thunderstorms in parts of the Plains, Missouri Valley and Ohio Valley. Dew points are well into the 60's if not even into 70s at areas in question. weather.us/observations... TT

Looking at the map of dew points across the continental USA one can see the plume of tropical moisture that has been affecting the Southwest. The higher the dew point value, the more moisture in the air. weather.us/observations... TT

It's August the 29th, one of those "where were you on that day?" type of days in the US weather history. 20 years ago today, hurricane Katrina made landfall in Louisiana. Here's a radar frame from that day: weather.us/radar-us/891... TT

Here's a look at observed weather across the continental US as of 2 PM CDT. Flooding is a concern today in parts of the country, such as in southern and central Plains and in the Intermountain West. weather.us/observations... TT

Shown is a scenario of possible tropical cyclone center tracks by different ECMWF ensemble members. As Erin rides into the sunset, a new system is possible in the western Atlantic. It is the season, afterall... weather.us/cyclone-trac... TT

Erin is now swirling away from the US east coast but due to its sheer size, tropical storm warnings are still in effect for parts of North Carolina and Virginia while a tropical storm watch is in effect in Bermuda. weather.us/satellite/73... TT

While the eye of Hurricane Erin is staying offshore, it is a large hurricane, so impacts are expected in the form of tropical storm conditions and storm surge. Weather in North Carolina's Outer Banks should deteriorate soon. weather.us/satellite/72... TT

An era has ended in the history of weather satellites. At 15:26:06 UTC, NOAA-15, the last of the POES satellites, went silent as it was decommissioned. Yours truly was able to receive the final image loud and clear from his home office in Estonia using his personal equipment. TT

(Phrasing refined) Here's a look at the category 4 hurricane Erin in imagery from GOES-19. While weather impacts are being felt from Erin's outer bands, its eyewall with the absolute worst conditions is expected to stay offshore. weather.us/satellite/74... TT

Meanwhile, less than an hour ago, polar-orbiting NOAA-19 satellite was passivated after a battery failure, less than a week shy of its scheduled decommission. Era of the old POES satellites with an analog APT transponder ends next week with the decommissioning of NOAA-15. TT

Here's the latest satellite imagery of Tropical Storm Erin from GOES-19: weather.us/satellite/43... TT

As illustrated by this product from 00 UTC ECMWF EPS, there is still a lot of uncertainty involved with the forecasts of what Tropical Storm Erin is going to do. Recommendation continues to be to stay calm, and follow latest advisories from the NHC. weather.us/cyclone-trac... TT

Say hello to Tropical Storm Erin. While it seems it might become a topic of discussion in the western side of the Atlantic soon, currently it is early enough that the best one can do is to stay calm and just monitor it for further developments: weather.us/satellite/29... TT
