Flooding downpours to unfold in Northeast as Hurricane Erin spins offshore
Tropical moisture sent northward by Hurricane Erin will trigger downpours that can lead to flash flooding in parts of the Appalachians and Northeast from Wednesday into Wednesday night, AccuWeather meteorologists warn. The heaviest rain will come from a stalled weather front draped across the region, rather than directly from Hurricane Erin. A pocket a dry weather could separate the two areas of rain. "In a worst-case scenario, several inches of rain could fall in just a few hours along the boundary of tropical moisture, leading to major flooding in urban areas and along smaller streams," said AccuWeather Vice President of Forecasting Operations Dan DePodwin. Rainfall rates may reach 1 to 2 inches per hour, with an AccuWeather Local StormMax™ of 8 inches expected for this event. Should these conditions materialize, significant flash flooding could result, inundating some highways and low-lying neighborhoods with deep water, potentially stranding vehicles and severely disrupting travel. From Wednesday into Wednesday night, the primary area of concern for heavy rainfall and localized flash flooding extends from upstate New York and southern New England to New Jersey, Pennsylvania, Delaware, Maryland and Virginia. Torrential downpours are expected to be highly localized, but forecasters anticipate pockets where a more concentrated swath of heavy rainfall could lead to an elevated flood the app? Unlock AccuWeather Alerts™ with Premium+ The highest risk for concentrated downpours is expected in parts of central and eastern New York, with another corridor extending from southern New Jersey and the Philadelphia area to Long Island, southern Connecticut and Rhode Island. A separate narrow band of heavy rainfall may also develop along the Allegheny Mountains, stretching from western New York through western Pennsylvania into northern West Virginia. As tropical moisture shifts northward, the zone of torrential downpours is expected to lift into New England before gradually diminishing by Thursday. Around that time, moisture on the periphery of Hurricane Erin may bring occasional wind-driven showers to portions of the mid-Atlantic and southern New England coasts. Thursday is also expected to bring the most hazardous surf conditions along much of the Northeast coastline. Want next-level safety, ad-free?

Severe storms, torrential downpours to erupt in eastern, central US ahead of July 4th holiday
Thunderstorms will erupt as the decaying heat dome gives way, feeding on the lingering hot and humid air across parts of the central and eastern United States. These storms are likely to cluster near advancing cool air boundaries. Some of these storms will be severe and/or bring flooding downpours, AccuWeather meteorologists warn. A prime area for both severe thunderstorms packing strong wind gusts and torrential downpours that can trigger dangerous flash flooding will stretch from parts of the central Appalachians to southern Virginia and westward into parts of the Ohio Valley. "A wedge of cooler air has settled over the Northeast but stalled across parts of the central Appalachians, creating a focal point for downpours and potentially severe storms." Some of the same areas in West Virginia, Virginia, Maryland and Pennsylvania that experienced flash flooding in the past couple of weeks will be at risk for flooding again due to the incredible amount of moisture in the atmosphere that will be squeezed out like a sponge. Intense downburst winds and small hail can accompany some of the storms into the early evening. Heavy rainfall can occur at any time through Friday night, before being renewed on Saturday. Rainfall rates in the most extreme cases can exceed 2 inches per hour, which is more than enough to turn drainage culverts, city streets and small streams into raging torrents. A storm and trailing cool front will slice across the Great Lakes through Friday night, before reaching the Northeast on the app? Unlock AccuWeather Alerts™ with Premium+ As the front advances, it will become a new focusing point for locally severe thunderstorms in the Appalachians and parts of the Atlantic coast. Flooding downpours and strong, localized wind gusts will pose the main threats to travelers and those spending time outdoors. A couple of the strongest storms on Saturday afternoon could spawn brief tornadoes. Perhaps the most likely spot for that will be over New York's Hudson Valley. Farther northwest, a new storm and front will gather moisture and momentum over the northern Plains on Friday then the Great Lakes region and part of the central Plains on Saturday. From high winds and damaging hail to flash flooding and powerful wind gusts, all modes of severe weather will be possible with storms into Saturday. The AccuWeather Local StormMax™ wind gust for Friday evening is 90 mph but will increase to 95 mph on Saturday, as the intensity of the storms is likely to peak later in the day and evening as the storms move into central and southwestern Minnesota. Later in the weekend, heavy and gusty to locally severe thunderstorms will tend to press southeastward and extend from Wisconsin to the High Plains of Colorado, Wyoming and northeastern New Mexico. In the zone from southwestern Wisconsin to northeastern Kansas and southeastern Nebraska, a greater concentration of severe weather is likely, with some storms capable of producing damaging hail, a few tornadoes and powerful wind gusts. Aside from the various pockets of severe weather this weekend, storms in parts of the middle Mississippi Valley and Florida can be especially drenching with locally gusty winds as well. In contrast, much of the West and the southern Plains will tend to be free of rain. The same storm and trailing front over the central Plains and western Great Lakes will push to the south and east on Monday. The major Midwest hubs of Chicago, Detroit, St. Louis and Indianapolis are likely to be dealing with severe weather at some point on Monday afternoon and evening. The same setup may advance into parts of the Northeast and southern Appalachians on Tuesday. Want next-level safety, ad-free?

Flood watches issued as storms move through Florida. See how much rain to expect
Much-needed rain is falling in Florida. However, so much rain is expected to fall a flood watch has been issued by the National Weather Service for seven counties. "In a typical May, 3 to 4 inches of rain will fall across much of the Southeast, but this storm has the potential to drop double that amount in two days' time or less," AccuWeather said. Forecasters also warned storms moving in from the Gulf could bring isolated tornadoes and gusty winds across the Southeast. ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location The National Weather Service warned dangerous rip currents are present along most of the East Coat and along the Panhandle. Days before graduation, a Sebastian River High School student died after being caught in a rip current Friday, May 9. A SpaceX launch scheduled for Mother's Day, May 11, was scrubbed late last night amid rain and thunderstorms at Cape Canaveral. The Falcon 9 launch has been rescheduled for 11:36 p.m. tonight, May 12. More than 84% of the state has been suffering from abnormally dry to extreme drought conditions for weeks. While rain early this week will be a welcome reprieve, current forecasts call for extremely warm, sunny days later this week and into the weekend. The National Weather Service issued a flood watch through 8 a.m. May 13 for seven counties: Broward Collier Glades Hendry Miami-Dade Monroe Palm Beach The National Weather Service Miami warned 3 to 6 inches of rain could fall between Monday and 8 a.m. Tuesday, with some areas possibly getting up to 8 inches. "The area most at risk for multiple inches of rain will be closer to the source of moisture, from northern Florida into far southeastern Alabama and southern Georgia, where the AccuWeather Local StormMax of 10 inches can occur," AccuWeather forecasters said. "While flooding downpours will remain the primary concern in any storm, an isolated or tornado or two cannot be ruled out."

Multiple hazards expected: strong winds, blizzard conditions and severe storms on tap for Rockies, Plains
Following an active weather pattern across the nation over the weekend, AccuWeather meteorologists warn that another storm is on the horizon for the upcoming week that could spread a burst of snow, blustery winds and even the risk for severe thunderstorms. The storm's energy will move into the West Coast to start the workweek, ushering in a wave of steady rain, coastal winds and high-elevation snow through Monday night. "Another round of heavy snow across the Sierra will occur with this storm Sunday night through Monday, with feet of snow expected across the highest terrain. Heavy snow will reach down to most of the major passes, with transportation routes like Donner Pass once again expected to see 1-3 feet of snow after seeing similar amounts just a handful of days ago," explained AccuWeather Meteorologist Grady Gilman. Forecasters warn that travel can become dangerous to down right impossible across some passes Monday when the heaviest snow is expected. Gusty winds at the higher elevations can quickly reduce visibility due to blowing snow. Travelers are urged to check the road condition reports before starting their trips and be prepared with items like chains and emergency kits. Burst of snow across the Rockies, Plains As the storm transitions over the Rocky Mountains late Monday through Tuesday, heavy snow is projected to develop across portions of Idaho, Utah, Wyoming and Colorado. The greatest snow totals are forecast to spread across the highest peaks in Colorado and Wyoming, where the AccuWeather Local StormMax™ of 30 inches can occur. "The system will then emerge east of the Front Range later Tuesday, bringing accumulating snow across the Interstate 25 corridor of Colorado through Wyoming as well as parts of interstates 70 and 80," noted Gilman. Gilman added that snow will total 3-6 inches, with 6-12 inches possible locally on the northern side of the storm across parts of Iowa and into Wisconsin. Though the exact track of the storm will ultimately result in the final location of the heaviest snow; the gradient between notable snowfall amounts and no snow will be significant. Locations across eastern Colorado into the Central Plains will observe a spurt of mild conditions ahead of the storminess. Places like Denver and Wichita, Kansas, are projected to have temperatures climb into the upper 70s Fahrenheit on Monday before the storm begins to track into the region. In Wichita, Tuesday afternoon highs will rise even higher than on Monday into the lower to middle 80s F, which would be the warmest day so far this year if it comes to fruition and even challenge daily records. The daily temperature record for March 18, in Wichita is 83 degrees F, set back in 1921. Gusty winds to spark fire threat for some, blizzard conditions for others Another important factor for this pattern will be the return of boisterous winds from the Rockies to Plains into midweek. However, locations farther east will not escape the gusty pattern as the storm transitions across the Great Lakes and Northeast later this week. On Tuesday, winds will ramp up from southeastern Colorado and New Mexico into Texas, Oklahoma, Kansas and Nebraska. Widespread gusts upwards of 40 mph will be possible across this zone, with a corridor of winds exceeding 50 mph across several states. Peak wind gusts are expected to develop across central and eastern New Mexico, where gusts to 60-70 mph can occur and the Local StormMax™ of 90 mph is possible. While the gusty winds will create areas of blowing dust that can impact travelers, they can also be strong enough to bring down tree branches and powerlines, resulting in power outages for some. Tuesday into Wednesday, as the winds transition north and eastward into the Plains where accumulating snowfall is expected, forecasters also warn that blizzard conditions will be possible across a narrow the app? Unlock AccuWeather Alerts™ with Premium+ Across the South Central states, the combination of strong winds, dry conditions and low humidity levels will result in a high fire risk on both Monday and Tuesday, particularly across eastern New Mexico and West Texas. Forecasters warn that residents should avoid outdoor burning and be mindful of anything that could potentially spark fires, as any that develop could spread rapidly. Severe thunderstorm risk along the warm flank of the storm Late last week and over the weekend, the intense storm activity resulted in devastating damage to the Central and Southeast states with at least 35 fatalities reported. The risk into midweek is not currently projected to compare to the destruction observed over the last several days, forecasters say, but storms that develop Tuesday night can still produce gusty downpours and hail as they sweep through parts of northeast Oklahoma, eastern Kansas, far northwestern Arkansas and Missouri. "The low pressure system will strengthen fairly rapidly once it emerges east of the Rockies as upper-level energy supports the storm system. However, moisture will notably be lacking with this storm and a severe weather outbreak like we saw this weekend is not anticipated at this time," noted Gilman. "On the warm side of the system gusty, hail-producing storms can occur Tuesday across eastern Kansas, Oklahoma and into Missouri with 'some risk' for severe thunderstorms. This threat will likely continue into Wednesday farther east into the mid-Mississippi valley," highlighted Gilman. Want next-level safety, ad-free?
