Amazing Satellite Animation of the Volcanic Pressure Wave

By -

Saturday, we walked about the barometric pressure wave from the Tonga volcano explosion as it moved across the United States. For example, the red line (below) shows the very rapid fluctuation in barometric pressure at Washington, DC. 

The Pacific GOES-17 weather satellite's sensors (not of the type you see in television weathercasts) was used to created an animation of the wave as emanated from the eruption. A screen capture is below.

The animation is here. Just amazing. Thanks to William Barlow for the animation.

A couple of tornadoes, hail and wind gusts to 65 mph are possible with these storms. This includes NYC and Philadelphia.  1:05pm. The tornado risk has been extended northward into New York. The brown area has a significant risk of tornadoes. Remember: if a tornado warning is issued, go to your basement and get under heavy furniture like a pool table. Of, if your basement is finished, get into the bathroom. Go ahead an put a couple of water bottles and, if appropriate, diapers in your shelter area. Wear shoes.  If you don't have a basement or safe room, go to the lowest floor and get into a bath or closet in the middle of your home. Children should be put in the bathtub.  I'll update later today.

Pink is a winter storm warning for significant icing. Deep green is a winter storm watch. I don't know why this is still a watch. If I were on the forecast desk I would have a winter storm warning for icing.  Dark blue is a winter weather advisory, a lesser condition, for icing.  Here is a view of the entire watch/warning/advisory area.

Power outages may occur in this areas. Deep blue i...
