Record rain, darkness: Seattle braces for floods, mudslides

Record rain, darkness: Seattle braces for floods, mudslidesRecord rainfall and darkness has hit Seattle as a major storm begins to lift across western Washington on the first day of winter, though the region is still at risk for flooding, mudslides and avalanches. Friday became the wettest day in Seattle in the past 10 years, and the most rain recorded for Dec. 20 since record-keeping at Seattle-Tacoma International Airport began in 1945. The National Weather Service said the airport recorded 3.25 inches (8.25 centimeters) of rain Friday, making it also the fifth rainiest day in city history.

Weather whiplash to bring warmup, heavy rain and flood threat followed by Arctic blast to Northeast

Weather whiplash to bring warmup, heavy rain and flood threat followed by Arctic blast to NortheastAs the holidays approach and many may find themselves dreaming of a white Christmas, Mother Nature has a different idea up her sleeves. The weather pattern will soon be reversed in the northeastern United States, allowing wintry landscapes to transform into a sloppy, muddy mess instead.Forecasters are closely watching a storm system that is expected to take shape and track toward the Great Lakes early next week — and it will be the player that will help to flip the weather conditions in the East. As wintry weather and yet another snowstorm are predicted for portions of the Midwest, surging warm and moist air will race out ahead of the system.Temperatures are expected to rebound to the 30s over the northern tier to near 50 F in parts of Virginia as a southerly breeze develops on Sunday.On Monday, temperatures are forecast to surge into the 40s across the northern tier and the 50s and 60s across part of the mid-Atlantic region. The warm air combined with rain will dissolve the deep snow over part of the Northeast, potentially leading to flooding issues for some communities. Recent storms have buried parts of New York state and central and northern New England under as much as 1-3 feet of snow in the last couple of weeks.

The last of the snow is falling over parts of New Jersey after leaving behind power outages in the northwest part of the state. (AP Photo/Seth Wenig) That snowcover contains a significant amount of locked-up moisture, called the snow-water equivalent.Within the existing snow on the ground, there is between 1 and 5 inches of water as of Thursday, Dec. 5.Many areas, including those places where deep snow is on the ground, may stay well above freezing Sunday night, which can allow the snow to soften up. This image was taken from the National Operational Hydrologic Remote Sensing Center on Thursday, Dec. 5, 2019. (NOAA) Some of the deep snow may harmlessly melt from Sunday to early Monday before the storm and its soaking rain arrives, but there is a risk that surging temperatures, moist air and drenching rain may cause a rapid meltdown of the existing snowcover from later Monday into Tuesday.Instead of releasing the 1-5 inches of water by itself, another 1-2 inches of water may be added in depending on the intensity of the rainfall that occurs. "Since the ground is not frozen, some of the melting snow and rain will be absorbed by the soil and should avoid disastrous stream and river flooding," Dale Mohler, AccuWeather senior meteorologist, said.However, some quick rises on small streams are likely with minor flooding possible in low-lying areas that are prone to flooding during heavy rain or spring thaw events. Some of the rivers may surge to bank full as well."Even if only part of the snow melts and only a light amount of rain falls, piles of snow along streets and highways that are blocking storm drains can lead to urban flooding," Brett Anderson, AccuWeather senior meteorologist, said.Anderson said that property owners should make sure that runoff has easy access to storm drains ahead of the system's arrival to reduce the risk of flooding as a precaution."Even in some of the major cities along the Interstate 95 corridor from Washington, D.C., to Philadelphia and New York City where there is no appreciable snow on the ground, enough rain can fall to cause travel delays and ponding on roads that drain poorly," Dave Bowers, AccuWeather forecaster, said.Ski resorts in the region that have gotten off to their earliest start in recent years will take a hit from the storm. Those seeking ideal ski conditions are encouraged to hit the slopes into Sunday, before the rainstorm arrives.Along with bringing a swath of heavy snow to part of the Upper Midwest, next week's storm is predicted to unleash Arctic air in its wake later Tuesday and Wednesday. Remaining areas of slush and standing water can freeze as temperatures plummet across the northeastern U.S. There is a chance that the cold air may catch up with the back end of the rain and cause a period of snow at the tail end of the storm at midweek.Since the storm will be weak rather than strong, it's possible that a secondary storm may develop along the push of frigid air, according to AccuWeather Chief Broadcast Meteorologist Bernie Rayno."I am pretty convinced that a storm is going to form along this boundary [between warmer air in place and colder air surging] into the Carolinas Tuesday night. Then, the question becomes does the storm goes out to sea and the cold front blasts out to sea? Or, does the storm have enough energy because of all of the energy associated with the jet stream that the storm strengthens? And, if it does, it won't go out to sea. It will come up the coast. If the storm does strengthen, you've got to worry about a snowstorm," Rayno said.The I-95 corridor of the mid-Atlantic and eastern New England could face snow if the latter and stronger scenario unfolds. If a weaker secondary storm develops, then it will likely push out to sea. If a secondary storm forms and it strengthens enough, it may bring snow to the Northeast. No indications are currently pointing to a big snowstorm developing and rather it could be more of a nuisance snowfall, according to Rayno.However, this type of weather pattern has yielded major snowstorms in the past, and meteorologists will have to keep a watchful eye on how all of the weather players come together, Rayno added.AccuWeather meteorologists are also tracking the potential for yet another significant storm toward the middle of the month, warning that it could be disruptive to the eastern U.S. Download the free AccuWeather app to check the forecast in your area.

Heavy rain, locally severe storms to soak the central US this weekend

Heavy rain, locally severe storms to soak the central US this weekendTropical moisture streaming into the central Plains from the tropical systems in the East Pacific Ocean will help to fuel severe thunderstorms and downpours across the region this weekend.Drenching rain developed across the Dakotas and northern Minnesota Friday evening and continued into Saturday morning as a storm system began to strengthen over the region.Residents woke up to flooded roadways as over four inches of rain fell in Fargo, North Dakota, Friday night. Radar-estimated rainfall shows similar rainfall totals across much of the area.Fargo, North Dakota normally receives 2.05 inches of rain through the month of September.More showers are expected to develop across North Dakota through Saturday afternoon, while locally severe thunderstorms can produce hail and gusty winds in parts of Minnesota. While the heavy rain is not expected to be as widespread as Friday night, any quick downpour can increase the risk for flash flooding across the rain-soaked area.Farther south, the central Plains will be on alert for severe thunderstorms and rounds of heavy downpours into Sunday.The storm system over the northern Plains will pull tropical moisture from Lorena and Mario, near the western coast of Mexico, into the central Plains. At the same time, the system will bring a cold front into the region.Showers and thunderstorms will continue to develop from southern Iowa and northern Missouri through central Kansas into Saturday evening as the front approaches the warm and humid air over the area."Storms that fire up later Saturday will have the ability to produce flash flooding, hail, damaging wind gusts and there could be an isolated tornado," stated AccuWeather Meteorologist Tyler Roys. The biggest threat for tornadoes will be when storms first develop, but downpours, hail and damaging wind gusts will continue to be a threat into the evening hours."Those who are attending any high school or collegiate sporting events should play heed to all weather warnings and take shelter when told to do so."Motorists traveling on Interstate-35 and Interstate-70 in these areas should be aware of changing weather conditions, decreased visibility in times of heavy rain and ponding on roadways.While the severe storm threat will be gradually diminishing after sunset, showers and storms will continue the risk for flash flooding as they expand from Oklahoma and Kansas into northern Illinois through Saturday night.On Sunday, occasional downpours will once again soak much of the same areas as the cold front will be slow to exit the central Plains. But as tropical moisture is pulled farther north, drenching rain is forecast to spread into Illinois, Iowa and Michigan.Flash flooding will be most common in areas where the front stalls and brings multiple rounds of heavy rain to end the weekend. "This will have the ability to produce widespread rainfall totals of 1-3 inches with the AccuWeather StormMax™ of 6 inches," added Roys.Chicago; Kansas City, Missouri and Oklahoma City are forecast to be in the heavy rain area.Spectators heading the Kansas City Chiefs game on Sunday will need to be aware of possible road closures due to flooding and pack rain gear for the game.A line of locally heavy showers and thunderstorms along the cold front will begin to push south out of the central Plains Sunday night, while the bulk of the tropical moisture fueled rain spreads into parts of the Ohio Valley.The storm system will move toward the Northeast on Monday and drier air will settle into the northern and central Plains for the start of the work week.

Tropical Storm Humberto dumps rain on hurricane-hit Bahamas

Tropical Storm Humberto dumps rain on hurricane-hit BahamasTropical Storm Humberto lashed the Bahamas with rain and wind on Saturday, possibly slowing down relief efforts in the wake of the devastation wrought less than two weeks ago by Hurricane Dorian. The US National Hurricane Center said the center of the storm, packing maximum sustained winds of 50 miles (80 kilometers) per hour, was passing Saturday evening about 70 miles north of Great Abaco Island, one of the areas hardest hit by Dorian. Humberto was moving away from the Bahamas on a path taking it well off the east coast of Florida this weekend and early next week, the NHC said.

Hong Kong tense as weekend of protests begins with teachers' rally in rain

Hong Kong tense as weekend of protests begins with teachers' rally in rainOver a thousand Hong Kong school teachers braved thunderstorms on Saturday to start a weekend of anti-government demonstrations that some activists fear could see tougher police tactics on the city’s streets. Following the escalation in violence during the past few days, the demonstrations this weekend will provide a litmus test as to whether the protest movement can retain the broad support that it has appeared to enjoy. Demonstrators say they are fighting the erosion of the “one country, two systems” arrangement that enshrined some autonomy for Hong Kong since China took it back from Britain in 1997.
