Tropics Stay Weird. Also Fire Danger In New England Of All Places

There's a tropical storm watch today in frigid Newfoundland. Another tropical storm rose from the dead nearly a week after dissipating. Yet another one is pretty sitting and spinning over the same location, unleashing dangerous floods. 

Gorgeous satellite view of the Northeast this
morning. Big curved cloud shield is outer
edge of Hurricane Teddy. Just west of 
that cloud shield over Vermont that got
entrained in Teddy's circulation.Then
there's a narrow band of smoke-free
air in northeastern New York, with
more smoke coming in behind it from 
the west.

The weird tropical storm season of 2020 continues on. I'l also get to the fire danger in a bit, which is in part being caused by yes, a hurricane. 

TROPICAL STORM BETA 

I'll start with the relatively "least" weird one first. Tropical Storm Beta splashed ashore along the mid Texas coast last night. Maximum winds were estimated to be near 50 mph, and I think even that was generous. 

The problem is Beta is stalling just inland, and is drawing feeder bands of torrential rain into the Texas coast and into southwestern Louisiana all day today and into tomorrow.

This location can NOT be worse than it is.  Houston, still traumatized by the extreme Hurricane Harvey floods of 2017,  is at a high risk of some substantial flash flooding today. It won't be as bad as Harvey, but that's not much comfort. 

Three to six inches of rain has already fallen around Houston as of early this morning, and at least another four inches is due today. Flash flooding is already ongoing in the massive Houston area, and that is likely to get worse as the day goes on. Flood warnings are up for most area creeks and rivers.  There are lingering storm surges along the coast, and that would limit the ability of creeks and bayous to drain into the Gulf of Mexico.

The torrential rains are likely to move into southwestern Louisiana which was totally wrecked by Hurricane Laura last month. Those tarps over destroyed roofs might not hold up to this much rain, adding to the wreckage of severely damaged houses. Renewed flooding will interfere with hurricane cleanup, and create added damage.  

TROPICAL STORM PAULETTE

This one has risen from the dead. Over a week ago, Hurricane Paulette smacked Bermuda with 90 mph winds, then raced off to the North Atlantic Ocean to die in the cold waters up there. 

Turns out Paulette is some kind of zombie. The remains of Paulette moved south into somewhat warmer waters kind of near the Azores. As of last night, it was reborn as a 60 mph tropical storm.

Paulette has turned east heading slowly toward southern Portugal, but will never get there. Cooler ocean water and high upper level winds should kill Paulette again over the next few days. However, there are some suggestions that its remains could turn on a dime and move westward again. 

If the ghost of Paulette gets far enough west and loses the upper level winds, who knows? It could become a zombie storm again. That's unlikely, but the way this year is going, you never know. 

HURRICANE TEDDY

Hurricane Teddy is gradually losing its tropical characteristics, but is still only half way through that process. When hurricanes do this, their areas of high winds expand.  Teddy is moving north toward Nova Scotia and is expected to give them a pretty nasty blow later today, and the bad weather will move up toward Newfoundland tomorrow. 

As of early this morning, Teddy still had top winds of 105 mph, and hurricane force winds extended as far as 100 miles from its center. That's a big area for a hurricane. 

That set up is helping Tedday cause huge waves and elevated water levels along the Atlantic Coast from Newfoundland to Florida. Coastal flooding is ongoing up and down the East Coast, even as skies remain sunny well outside Teddy's core of clouds and rain.

New England is on the western edge of Teddy's expanding wind field, so breezy to gusty north winds will come through today, especially east of the Connecticut River.

New England is in a drought. The winds today, gusting to 30 mph or more in the eastern half of the region,  could help spread any fires that start.  So I guess we're getting a very mini version of what's been going on in the western United States for weeks now. 

Red flag warnings that indicate fire danger are up for almost all of New Hampshire, Massachusetts, Rhode Island and southwestern Maine. 

Here in Vermont, the fire danger isn't quite as high because the wind will be lighter than areas to our east. However, the northerly breezes, low humidity and especially the very dry conditions from this month's lack of rain raises the risk of fires. 

Note that smoke from western wildfires is getting caught up in Teddy's circulation, so we will be back to smoky skies overhead, especially this afternoon. We first started noticing this return to smoke overhead yesterday, ,and I think it might thicken up some this afternoon. 

Some relief from the dry weather is possibly due later in the weekend and early next week. Two fairlky wet cold fronts, one Sunday night, the other Monday night and Tuesday, have the potential at least to give us some decent rains for once.

Sally Threat, Atlantic Tropics Busy As They Can Get And A Frosty Vermont

 I'll get to the incredibly busy swarm of tropical storms and hurricanes out in the Atlantic Ocean in just a sec, but here's a heads up for us Vermonters. 

As this map from the National Weather
Service in South Burlington shows,
low temperatures in Vermont will
be in the 30s tonight, with some upper
20s in the coldest hollows.

It's unfortunately time to start thinking about putting your gardens to bed for the fall.  At the very least, many of us should cover them up to protect them tonight. 

Frosts are coming to a fair number of towns in northern Vermont and New York tonight and early tomorrow morning. This one will be more widespread than the few scattered pockets we had Saturday. The chill will be deeper, too.

On Saturday. there were just a couple of frost advisories in the North East Kingdom and the Adirondacks.  And just a couple cold hollows actually got frost. 

Tonight, the Northeast Kingdom and Adirondacks are under a freeze warning, so that would be a crop killer in those areas unless you harvest today. It'll go below freezing there. 

A frost advisory is up for the rest of northern Vermont except the Champlain Valley. Remember, air temperature is usually measured five feet off the ground, but on clear, calm nights like what's expected tonight, the ground can be colder. 

So, if it's say, 35 degrees, you can still have a frost damaging your garden plants. 

Pretty much all of Vermont will be in the 30s by dawn tomorrow, except areas near Lake Champlain, which will stay up in the low to mid 40s. 

Even many valleys in southern Vermont could have a touch of frost. 

So take care of your plants!

It'll warm up a little during the rest of the week, but beware: Another cold shot is coming up late in the week and the weekend, and this one will be even chillier than the one we've got coming in now. Frost might be even more widespread in the weekend than it will be tonight. Even the Champlain Valley will be in play then.

Now on to much more dramatic weather:

HURRICANES AND TROPICAL STORM SWARM

As of early this morning, there were five, count 'em five, hurricanes, tropical storms or tropical depressions in the Atlantic. That ties a record set in September, 1971 for the most simultaneous such storms on record.  

An incredibly busy map of the Atlantic Ocean
with numerous tropical storms or things
that are close to tropical storms.

So far, only one of these storms is threatening the United States, but that one still looks like it will cause a lot of damage along the Gulf Coast. I'll take all these one at a time, in no particular order, except for the most dangerous one, Tropical Storm Sally

SALLY:

Tropical Storm Sally last night looked like it got more intense, but so far, the more vibrant thunderstorms that blossomed with the storm last night haven't translated all that much toward a more powerful storm. 

Sustained winds were 65 mph with Sally early this morning, up just a little from yesterday. But it was still expected to strengthen into a hurricane. 

Even if it doesn't, Tropical Storm Sally would still be a nasty beast for the Gulf Coast. It's forward motion is still quite slow, and it will probably slow down even more.  That gives the storm a big opportunity to create a huge storm surge along parts of the Gulf Coast.

The slow forward motion would give Sally a chance to dump a tremendous amount of rain on part of the Gulf Coast.  Some spot might get close to 20 inches of rain. 

There's also the possibility that Sally could abruptly strengthen today before it makes landfall sometime on Tuesday. 

The one glimmer of good news with Sally is the forecast track is a little east of what it was yesterday. That means impacts to New Orleans might be a little less.

PAULETTE:

Talk about finding a needle in a haystack! The island of Bermuda is just a 20-mile wide speck in the 2,000 mile wide Atlantic Ocean. Nevertheless, Hurricane Paulette was able to make a "perfect" track so the eye of the storm went right over Bermuda this morning. 

Paulette had top winds of 90 mph when it hit.  I haven't heard many reports on how Bermuda is faring with such a direct hit, but the island is pretty resilient and well-prepared for hurricanes, so that's good news. 

Hurricane Paulette will strengthen for a time as it heads northeastward away from Bermuda. It will eventually weaken in the cold waters of the North Atlantic in a few days.  This storm is no threat to the United States, aside from rip currents on East Coast beaches.

TROPICAL DEPRESSION RENE

Rene was a tropical storm for awhile, but weakened to a depression as it struggled with strong upper level winds. It was barely hanging on as a depression this morning as there are a few thunderstorms around it.  As of 11 a.m Rene was pretty much gone. Yawn. 

TROPICAL STORM TEDDY

Teddy blossomed into a tropical storm last night. It's still in its formative stages way out in the Atlantic Ocean with top winds of just 40 mph.  

The bad news is Teddy is expected to become a major hurricane with top winds of 115 mph once it reaches the central Atlantic well southeast of Bermuda. The very good news is that Teddy is no immediate threat to land, and stands a very good chance of staying out to sea away from populated areas. 

TROPICAL DEPRESSION #21

This little thing formed overnight off the west coast of Africa. It was upgraded to Tropical Storm Vicku late this morning, but it is not expected to last long.  Vicky will get blasted by strong upper level winds. Don't worry about this one. 

Another disturbance just emerged into the Atlantic Ocean from Africa. This one stands a good chance of becoming a tropical storm eventually.
