However, since the shutdowns, U.S. markets have recovered to nearly the levels that were at prior to the pandemic.Despite stock recoveries, other important economic measuring sticks like unemployment remain historically high.Recent losses come as COVID-19 cases spike again across the country. Health experts warn that the U.S. is at a perilous point in the pandemic with rising hospital and death rates ahead of winter months. 715

The fourth nor'easter in three weeks already is closing schools and canceling thousands of flights Wednesday as it's expected to dump record springtime snow in the Northeast.A day after the official beginning of spring, the storm will bring heavy snow, strong winds and even coastal flooding to some areas. It has potential to be one of the most significant and most disruptive snowstorms this late in the season, CNN meteorologists said."If the current forecast pans out, this nor'easter will dump more snow on Washington, Philadelphia and New York than the three earlier storms combined," CNN meteorologist Brandon Miller said.More than 70 million people are under a winter storm watch, warning or advisory from the southern Appalachians to Boston.The storm will move away from the region by Thursday but not without first hitting coastal New England and Maine.Latest developments? More than 4,100 flights are canceled Wednesday due to the storm, according to the tracking site Flightaware.com.? Public schools in New York City, Philadelphia and the District of Columbia are closed Wednesday.? The storm already dumped 13 inches of snow in Greencastle, Pennsylvania, and blanketed Smith Crossroads in West Virginia with 9.2 inches.Snow disrupting nation's capitalWashington will likely see 4 to 6 inches of snow, with some models hinting at much higher totals for the District. Areas west and north of the city are likely to see close to a foot of snow."It's been 75 years since Washington has had 5 inches of snowfall or greater this late in the season," Miller says.Track the storm with high resolution auto-updating graphicsThe inclement weather caused closures for much of the federal government. The White House and State Department canceled all public events for the day. However, the House and Senate are planning to work Wednesday as Congress tries to finalize a spending deal.Philadelphia could see up to a foot of snow. The City of Brotherly Love may get its biggest snowfall after the first day of spring in more than 100 years.For those in other parts of Pennsylvania, the storm was already well underway Wednesday morning. Thile Kreider posted an Instagram video of the snow blanketing her yard in Manheim.New York could break 1958 recordWind gusts and snow reached New Jersey and New York City on Wednesday morning. Ten inches to more than a foot is forecast in the New York City area before the storm departs early Thursday.But Central Park in Manhattan may only receive 4 to 6 inches of snow, CNN meteorologist Chad Myers said, explaining it's more likely snow will accumulate in areas at higher elevations."If New York gets 12 inches of snow -- the National Weather Service currently has a high-end potential of 13 to 21 inches -- it would be its largest snowfall ever recorded after the first day of spring," Miller says.The current record is 11.8 inches, set on March 21, 1958.With these late winter storms, it is difficult to predict snowfall amounts because of the mixing of warmer air. In some of the earlier nor'easters, the air near the ground has stayed warm enough that places like New York have seen lots of snow fall from the sky but had little accumulation. An urban heat island effect is plausible once again with this spring storm.Boston stayed on the warmer side in the first two nor'easters but then got walloped with snow during the third storm this month. The city is likely to see another 6 to 8 inches of snow, adding to the 20-plus inches it has already received in March.If Boston gets 10 inches, the city would have its third snowiest March on record.These late winter storms are likely to become more frequent with climate change. A study last week in the scientific journal Nature Communications ties extreme winter weather, specifically major snowstorms in the Northeast, to warming Arctic temperatures.Blizzard conditions likelyWith a forecast of heavy snow and winds more than 45 mph, blizzard conditions are possible.New York City could see sustained winds of 20 to 30 mph Wednesday, and coastal areas such as Cape Cod in Massachusetts are predicted to receive gusts up to 60 mph from midmorning Wednesday to Thursday.What is makes a snow storm a blizzardFlooding is a threat along the coast from Virginia to Massachusetts. Some of the worst coastal flooding could occur along the Jersey Shore, with high tides of 2 to 3 feet above normal possible.This will put a strain on already vulnerable coastal areas, which saw dramatic storm surges from the nor'easters over the last three weeks.The-CNN-Wire 4555

The current spike in COVID-19 cases is stressing the testing system across the country.As the virus spreads at unprecedented rates, more Americans are seeking COVID-19 tests. But in recent days, companies that make the tests and the supplies needed for them are struggling to keep up with demand."Those companies were operating on an allocation basis, and that just means that basically everything they make is going out the door," said Kelly Wroblewski, the Director of Infectious Disease Programs at the Association of Public Health Laboratories. "There is no reserve, so there's an increased demand in a lab for testing. There's no more reagent to be had, so to meet that demand, that lab has to use a different manufacturer's test."Wroblewski adds that along with issues in getting supplies, officials are also short on human resources — there is only so much lab capacity and only so many trained people to conduct the tests.The American Clinical Laboratory Association says the surge in demand for testing means some labs could reach or exceed their current testing capacities soon — meaning it could take longer for patients to get PCR test results back.Wroblewski says that it can take currently take anywhere from 24 hours to a week to get PCR test results back.With antigen tests, patients can get results back in less than 30 minutes. There is currently enough of a supply for antigen tests, but not all facilities offer them.Both lab groups stress that COVID-19 testing is important, but patients should be strategic."There's been a lot of emphasis put on testing, but testing is only one piece of the puzzle," Wroblewski said. "It gives you some information, and if you're not going to do anything with that information — whether it be targeted closures. whether it be staying home and isolating — we're not going to stop the spread of disease."As far as getting more tests, it's going to take a while. Wroblewski says it could take up to six months or more to increase production capacity significantly. Labs don't expect to see a ramp-up in supplies until early 2021. 2090

The Federal Aviation Administration issued an emergency directive for inspections of certain Boeing 737 planes due to recent reports of engine shutdowns.The FAA issued an emergency airworthiness directive on Thursday for certain Boeing 737s that have been in storage for more than a week.According to the directive, a certain engine valve may be responsible for four recent reports of engine shutdowns. Agency officials suspect that the valve may become corroded during storage, causing it to remain stuck in the open position.The directive requires that any Boeing 737-300, -400, -500, -600, -700, -700C,-800, -900, and -900ER that have been in storage for a week or longer undergo an inspection before being put back into use. The directive also requires inspections for any of those Boeing models that have completed "less than 10 flight cycles" at the time of the directive after coming out of storage.The inspection order was released the same day that CNBC reported that Boeing told lenders to expect fewer deliveries of its 737 Max planes that initially expected. The 737 Max, a plane Boeing has been developing for years, was grounded in 2019 after a series of crashes. 1185
