#Michael has taken and changed lives, left communities in ruins, and even altered the coastline itself. Some of the landmass of St. Joseph Peninsula State Park, just offshore Port St. Joe, no longer exists. It takes powerful storm surge and waves to do this.

Our moon is the largest in the solar system, relative to the size of the planet itโ€™s orbiting. So it appears fairly large during any full moon. But during tonightโ€™s biggest full #supermoon of 2020 itโ€™ll be near perigee, less than 222,000 miles away instead of the average 239,000.

Staggering #Dorian numbers. Gusts to 220 mph. Storm surge 18-23 feet. Pressure 910 mb. And slow 7 mph motion is only going to get worse - maybe down to zero at times. Canโ€™t think of many weather scenarios worse than slow-moving cat 5 over populated area.

Eye diameter of #Ian about 35 miles across, a larger hurricane after Tue night eyewall replacement cycle. Entire extent of hurricane force wind field of Charley 2004 would fit inside Ianโ€™s eye. This will produce a much wider swath of damaging wind, storm surge, flooding rains.

In many ways #Dorian is an even worse hurricane today than yesterday. Forward motion 24 hours ago was 7 mph, now essentially zero. A stationary major hurricane over low-lying populations is the worst. Also itโ€™s a bit larger now and high waves extend much farther from center.

Inner eyewall lightning outbreak before collapsing, new outer eyewall of #Ian taking over, so staying at current intensity a while, might weaken. Then could restrengthen before landfall. If not, slightly weaker, slow-moving majors produce massive surge, long duration wind & rain.

Why do Carolinas and Texas have nearly stationary tropical systems? Theyโ€™re trapped under massive, deep-layer ridge dominating eastern 2/3 of the country. No, theyโ€™re not strong over land, but they have onshore moist flow, upper-level outflow. No steering and no shearing.

When models start suggesting tropical cyclone development many days in advance in multiple parts of the Atlantic basin, while they might not be right about exactly when and where, it does indicate that the atmosphere is changing and itโ€™s about to get busy overall for September.

There is no need to cancel any planned trips you may have to any islands in the Bahamas that were not impacted by #Dorian . Grand Bahama and The Abacos were devastated and need help, but otherwise, cancellation of trips to the rest of the country will further hurt their economy.

Evacuation motivation: Slow forward motion -> long 2-day duration of #Ian winds when help might not come if you need it -> excessive rain adds to flooding, to heights that could exceed surge inundation forecast in evac zone -> blocked roads in aftermath, help also might not come.

We should stop calling systems like #Nicole a โ€œsubtropical stormโ€ and use โ€œhybrid stormโ€. Just like a hybrid car, which people understand, it runs on two kinds of fuels - warm water and temperature contrasts. And being a hybrid car or hybrid storm doesnโ€™t make it less dangerous.

Life-threatening winds of major hurricane #Ian just hours away from Florida peninsula. Don't tape windows, don't stay in mobile home. High rises? Evacuate from those in storm surge zones, and even inland don't stay on higher floors, where winds can be a category stronger.

When pressure in Katrina reached 902 mb over Gulf the day before landfall, it was at the time 4th lowest on record in Atlantic basin. It quickly fell to 6th after 895 in Rita and record 882 in Wilma. Now itโ€™s 7th, with Camille since reanalyzed to 900 mb. How fast history changes.

I am heartbroken over loss of life in NJ and NY from #Ida flooding. Rainfall and flood risk were well forecast. Challenge lies in communication for life-threatening water. To start, Iโ€™d favor something like โ€œmajor flood watchโ€ to give more visibility to @NWSWPC high risk days.

Intensification rate of #Lee has been impressive but didnโ€™t exceed Wilma 2005 that went from 60-kt storm to 150-kt cat 5 in 24 hours.

Just because you canโ€™t see the ocean from your Florida home doesnโ€™t mean it canโ€™t come see you in #Irma . Evac zones:

I asked family what theyโ€™d heard about the #Ida flooding. They said it was a โ€œ500-year floodโ€. Painful. Letโ€™s stop using that completely misleading terminology. Incomplete historical records, our changing built environment, and a warming world make that terminology useless.

Start of tornado outbreak imminent! Instability and shear apparent in this visible loop. PDS tornado watches up, now include Wichita Falls, OKC, Tulsa. Increasing flash flood threat in Oklahoma and Kansas as well. Live coverage right now and all night on The Weather Channel.

Officials saying don't wait until mandatory evacuations actually go into effect to leave. Farther you plan to go, sooner you should go, traffic backups Tue could be extreme. Only have to go far enough to be out of evac zone in structure safe from wind, not in mobile home. #Ian

One of the most concerning parts of the #Dorian track is how slow it gets near Florida. Storm surge and wind will likely be life-threatening, but letโ€™s also prepare for an inland flood disaster somewhere in southeastern U.S. That hazard has taken the most lives in recent years.

Impacts of Hurricane Matthew (2016) included 11 total fatalities in FL and 3 in GA, with more than 1.5 million customers losing power and extensive coastal wave and storm surge damage in those 2 states. The center of Matthew never made landfall in Florida or Georgia. #Dorian

Interestingโ€ฆ Thu eve Air Force will have 2 planes in the air: one goes into #Lee as usual, other does synoptic surveillance mission around Lee to drop sondes to improve model forecasts - similar to G-IV jet but lower altitude. Thanks to crews for all they do to help us prepare.

Air Force recon just went through the center northwest of Andros, and the data indicate #Isaias probably about a 55 mph tropical storm now. Weโ€™ll see how @NHC_Atlantic interprets the data. The storm is weaker but itโ€™s not done. Tropical storm warnings will still be up and legit.

If center of #Maria goes over Dominica, this will be only the second year on record that two Atlantic basin cat 5 hurricanes make landfall.

This should put to rest the idea that the storm surge in #Laura wasnโ€™t as bad as forecast. Maybe not in Lake Charles, but Cameron and especially communities east of there that experienced the radius of max winds on the east side got leveled.

Even if #Sally doesnโ€™t become a major hurricane defined by category 3+ on the wind scale, itโ€™ll likely be a major event with major impacts, including flooding rains. Forecast of forward speed less than 5 mph at landfall is at least as concerning as the max winds. #CategorySlow

Answering the many who have asked if they can or should drive into or within North Carolina today, be just as afraid of driving through flooding as you would driving into the winds of a hurricane or tornado. #Florence

We don't yet know what name TD 9 will get. TD 10 also forecast to become named storm tonight. One will be #Hermine , the other #Ian , but which will be which? If both become storms during 8-11 pm tonight, it might come down to which @NHC_Atlantic forecaster has faster fingers...

Go Tapeless! Do not tape windows for #Irma . Broken pieces will just be larger, deadly. Waste of time and money. Use shutters or plywood.
