A Stalled Weekend Front - Tracking Jose and Maria
There's a natural rhythm to the weather, an ebb and flow to the atmospheric currents rippling overhead. In recent years, warm season weather patterns appear to be slowing. Not every day, not every week; but with greater regularity.
This sluggish flow during the warm season could be related to rapid warming of the Arctic, impacting the speed and configuration of jet stream steering winds aloft. More research is needed to determine if this is a fluke, an aberration, or a real trend.
A cool front runs out of gas and stalls over Minnesota for the better part of 4 days. Waves of showers and T-storms may dump as much as 3-6 inches of rain on parts of Minnesota Saturday into next Tuesday. The MSP metro is forecast to stay on the drier, warmer side of this boundary; with 80s Saturday and Sunday.
MSP metro rainfall is about 1.4 inches below average this month - we could make up for that in a hurry.
Speaking of weather getting stuck, Jose is forecast to track east of Cape Cod, then do a U-turn, hitting New Jersey in 5 days.
Category 5 Maria may devastate much of Puerto Rico today. Say a prayer or two.
Praedictix Briefing: Issued Tuesday, September 19th, 2017:
*Jose is still classified as a Category 1 hurricane this morning, sitting about 350 miles south-southwest of Nantucket, MA.
*The main threats from Jose across parts of the Northeast coast will be dangerous rip currents and surf over the next several days while the system sits far offshore. Some stronger winds (with gusts of 40-60 mph) will also be possible, especially along coastal Rhode Island and Massachusetts south of Boston. Additional rainfall of up to 4” is also possible.
*Maria became a very dangerous Category 5 hurricane last night before making landfall on the island of Dominica around 9:15 PM ET. While it weakened a little after landfall, it is once again a Category 5 system with 160 mph sustained winds this morning. This “potentially catastrophic” storm (as quoted from the National Hurricane Center) will head toward the Virgin Islands and Puerto Rico over the next 24-48 hours. What impacts this system could have on the United States by next week are still unknown.
A Tropical Storm Warning is in effect for...
* Watch Hill to Hull
* Block Island
* Martha's Vineyard
* Nantucket
A Tropical Storm Watch is in effect for...
* The coast of Long Island from Fire Island Inlet to Port Jefferson
* New Haven to Watch Hill
Powerful Maria. Maria made landfall on Dominica overnight as a Category 5 hurricane with 160 mph winds. The storm did briefly weaken due to interaction with the higher terrain of the island, but the system has since restregthened. As of 8 AM ET, Maria has 160 mph winds and was moving to the west-northwest at 9 mph. Maria was located 85 miles west of Guadeloupe, or 170 miles southeast of St. Croix. (Satellite data: AerisWeather)
Other expected impacts on Puerto Rico and the Virgin Islands:
- Winds: Hurricane conditions later today. Winds will be strongest tonight into Wednesday. Winds atop and on windward sides of mountainous areas are likely to be stronger than surface winds.
- Rainfall: 10-20”+. This will cause flash flooding as well as the potential of mudslides.
Summary: Even though Jose is passing far offshore the Northeast coast over the next few days, we are still expecting to see some impacts across the region. These include gusty winds of 40-60 mph (particularly near the coast) as well as high surf, rip currents and a storm surge of up to two feet at high tide in spots. Meanwhile, Maria – a dangerous Category 5 hurricane – will continue to move toward the Virgin Islands and Puerto Rico over the next 24-48 hours. Impacts could be extensive in these areas, including over a foot of rain that will lead to flooding and mudslides, as well as a life-threatening storm surge of 6-9 feet. It is still too early to determine what impacts Maria could have on the United States into next week. We’re also tracking a cold front in the upper Midwest which has prompted an Enhanced Risk of severe weather across parts of the Dakotas and Minnesota today. Damaging winds, large hail and a few tornadoes will be possible as storms pop later today and move east into the evening.

The numbers from the second record-breaking storm that hit the US this

A New Study Shows that People Forget About Natural Disasters Really Quickly. Quartz explains: "Recently experiencing severe weather events such as floods, storms, and drought can make people more inclined to support policies aimed at adapting to the effects of climate change, but not by much and not for long. The relationship between exposure to extreme weather and support for climate policies is small, a new study finds. And it fades quickly; a month after an extreme weather event, there was no effect. “People respond to recent weather, whether it’s temperature spikes, severe storms, or other events,” says David Konisky, an associate professor in the School of Public and Environmental Affairs at Indiana University and an author of the study. “But the effects are small. Extreme weather is much less significant than other factors when it comes to attitudes about climate...”
10 Costliest Hurricanes in U.S. History? NOLA.com in New Orleans takes a look; number one on the list is Katrina: "The 10 costliest hurricanes in U.S. history, even when damage estimates are adjusted for inflation, all occurred in the past 30 years. All but two of them struck in the 21st century. The storms hit Florida (6), Louisiana (4) and Texas (2), as well as Alabama, Mississippi, New Jersey, North Carolina and South Carolina (1 each). Most of the big ones struck more than one coastal state. But it’s not just coastal states where costs mount. Once a hurricane comes ashore and weakens, cut off from the warm seawater that fuels it, it still carries immense amounts of moisture. As it moves hundreds of miles inland and breaks up, it continues to dump that moisture in the form of phenomenal rain that floods creeks and rivers, causing even more damage..."

Downtown Charleston is Flooding More, With or Without Hurricanes. Here's a story excerpt from The State: "...Charleston’s flood woes are a prime example of how a coastal community is experiencing the first-hand impacts of climate change and sea level rise, say some city officials, conservationists and federal scientists. “It is certainly becoming more of a topic and more obvious to people,’’ Nature Conservancy climate specialist Liz Fly said of the increased flooding. “Things are just happening more frequently. This really should be in the conversation about how to live with the water.’’ Like other coastal cities, Charleston has flooded for hundreds of years because it lies in a marshy environment. But statistics indicate flooding is worse now than ever. From the late 1950s through 2013, Charleston experienced a 409 percent increase in flooding, much of it from water that pools up periodically during high tides, according to the S.C. Department of Health and Environmental Control and the National Oceanic and Atmospheric Administration..."

U.S. Coastal Growth Continues Despite Lessons of Past Storms. We continue to flock to the ocean, in spite of rising seas and increasingly damaging storm surges. Here's a clip from The Washington Post: "Rising sea levels and fierce storms have failed to stop relentless population growth along U.S. coasts in recent years, a new Associated Press analysis shows. The latest punishing hurricanes scored bull’s-eyes on two of the country’s fastest growing regions: coastal Texas around Houston and resort areas of southwest Florida. Nothing seems to curb America’s appetite for life near the sea, especially in the warmer climates of the South. Coastal development destroys natural barriers such as islands and wetlands, promotes erosion and flooding, and positions more buildings and people in the path of future destruction, according to researchers and policy advisers who study hurricanes. “History gives us a lesson, but we don’t always learn from it,” said Graham Tobin, a disaster researcher at the University of South Florida in Tampa..."

Earth just sweated through the third hottest August and summer on record. The National Oceanic and Atmospheric Administration said Monday the globe last month averaged 61.5 degrees (16.43 Celsius), which was a degree-and-a-half higher than the 20th century average, but behind 2016 and 2015. The average temperature for June through August was 61.47 degrees (16.41 Celsius).

Editorial: Don't Cut NOAA. Yes, this might be a bad time to take a hatchet to NOAA's budget. For the price of a tall, soy vanilla latte you have access to what are consistently the most accurate, reliable weather forecasts and severe weather warnings in the world. Here's an excerpt from SavannahNow: "...While the national debt is real, and Congress and the president must do a better job of working together to cut waste and improve efficiency and bring fiscal sanity to Washington, there are better places to cut spending. Don’t cut agencies like NOAA that help keep this nation safe from hurricanes, at relatively low cost. NOAA’s annual budget is currently $5.6 billion, a small fraction of the federal government’s $1.2 trillion discretionary budget. The National Weather Service costs each American about $3 per year, the agency said on its website. Three bucks a head is a bargain for data that provides a great value to the public. If the accuracy of hurricane tracking could be improved, most Americans probably would be willing to pay even more..."

Renewable energy technologies are upending the century-old, centralized business model that that utilities have used to grow. The cost of electricity from offshore wind farms, once one of the most expensive forms of green energy, is expected to slide by 71 percent over the next two decades, according to BNEF. Solar, once so costly it only made sense in spaceships, now competes with coal and even natural-gas plants on cost. “I do think we’re experiencing the slowest trainwreck in history,” Steven Martin, chief digital officer at General Electric Co.’s energy connections unit, said at the conference. “We’re going to reach some point where the marginal cost of energy is zero.” Earlier this year, Germany shocked the renewable energy industry by handing out contracts to developers willing build offshore wind farms without subsidy. Spain has also seen zero subsidy tenders, according to Starace, who said he expects the trend to go global after beginning in Europe..."

This Liquid Coating Turns Windows into Solar Panels. Seeker has news of emerging technology with great promise: "A
Maryland company has been moving slowly and steadily for 20 years
toward a very ambitious goal — turning windows into transparent solar
panels that harvest energy from the sunlight that passes through.
SolarWindow Technologies is among the many energy companies looking for
ways to harvest solar power on a large scale. But SolarWindow's
proposition is to turn windows into solar panels by way of a thin
transparent coating applied to standard glass and plastic windowpanes.
The coating might not generate much power when slapped on your living
room window, but SolarWindow is aiming higher — quite literally. The
company hopes to eventually deploy the technology onto office buildings
and skyscrapers, generating energy from the acres of glass soaking up

We also know that warming leads to higher sea levels, which in turn increases the risk of storm surge, contributing to the damage brought by hurricanes. Climate change also warms oceans, adding energy that can fuel coastal storms. Compounding this, a warmer atmosphere can hold more moisture, so there can be more moisture for storm systems, resulting in heavier rainfall. The U.S. National Climate Assessment finds that there has been a substantial increase – in intensity, frequency, and duration as well as the number of strongest (Category 4 and 5) storms – in Atlantic Ocean hurricanes since the early 1980s, linked in part to higher sea surface temperatures. By late this century, models on average project a slight decrease in the number of tropical cyclones each year, but an increase in the number of the strongest (Category 4 and 5) hurricanes and greater rainfall rates in hurricanes (increases of about 20 percent averaged near the center of hurricanes)..."

Rogan talks about the foundation of our democracy. What he omits is that in the Fifth Amendment, the founders recognized the fundamental right of citizens to be free from government actions that harm life, liberty, and property. Our nation's climate system, including its atmosphere and oceans, is tightly tied to this right. James Madison, who drafted the constitution, said in 1818: "The atmosphere is the breath of life." In Texas and in Florida, we just saw our climate, infused by fossil fuel-created carbon pollution, infringe upon the inalienable right to life, liberty, and property. One of my co-plaintiffs, 10-year old Levi, lives on a barrier island in Florida. The federal government's contribution to our climate crisis, with the cooperation of the fossil fuel industry, directly violates this right, especially us as young people..."

Yes, Climate Change Made Harvey and Irma Worse. A consistenly warmer ocean didn't trigger the storms, but there's a high probability it amped them up, juiced them into stronger hurricanes. That, and higher sea levels magnified the storm surge associated with each storm. CNN reports: "The right time to talk climate change is now.It might seem premature when people in the Caribbean, Florida and Texas are still mucking out their flooded homes. And no, changes in our planet's atmosphere did not cause Hurricanes Harvey or Irma. But the consensus among scientists is that the effects of climate change, such as rising sea levels and warmer oceans, made those storms far more destructive than they would have been in previous decades. "The short version is, climate change makes these very bad storms worse," said Sean Sublette, a meteorologist with Climate Central, a nonprofit group that studies climate change. "It's not the approximate cause of the storm, but it makes these bad storms worse. And in the case of a really bad storm, climate change can make it totally disastrous or catastrophic..."
