Low pressure will spread a wide area of torrential rain across the Ohio Valley and the mid-Atlantic Ocean through Saturday, then move away from the East Coast by Mother’s Day and create high currents, rip currents and coastal flooding along the East Coast next week.
This storm system will first release a threat of severe thunderstorms in parts of the Southeast before becoming familiar on the East Coast at the start of the weekend.
Periods of rain and some thunderstorms inundated the Ohio Valley and the mid-Atlantic on Friday. Heavy rain will continue in the mid-Atlantic states for most of Saturday.
Heavy rain is expected along Interstate 95 from New York City to Philadelphia, Baltimore and Washington Friday night and Saturday morning.
Most areas will dry out overnight on Saturday as the low pressure system slides offshore, resulting in a dry Mother’s Day across much of the eastern United States. North Carolina.
An inch or two of rain is expected across much of the Ohio Valley and the mid-Atlantic, although it will spread over many hours, which will reduce flood risk in these areas. Locally higher amounts over 2 inches may be possible in some areas.
The greatest risk of localized flash floods will be in southern Ohio, western and central Pennsylvania, and West Virginia, where the soil is most saturated. These areas have captured up to 200 percent of the average rainfall over the past 30 days.
The National Weather Service released hours of flooding from parts of Ohio and eastern Kentucky to West Virginia, western and central Pennsylvania, Maryland and northern Virginia.
In addition, temperatures will be cooler than average due to continued clouds and rain. The gusty winds will only make you feel like you’re in your 30s and 40s from Boston to Philadelphia through Sunday.
Threats of high waves, rip currents and coastal flooding
The low pressure system will be in place off the coast of North Carolina by Mother’s Day, and won’t move much through the middle of next week.
This is because the jet stream would be well off in the north, so there wouldn’t be any atmospheric turbulence to push this system away from the east coast.
The high-pressure system will also be located over Maine and the Canadian province of Quebec. Clockwise winds around this elevation will combine with counterclockwise winds around the low pressure system near the east coast, resulting in a continuous inshore northeast wind.
This will be an exceptionally long-running event, with coastal areas experiencing wind gusts of 40 to 50 mph almost nonstop from Saturday to Wednesday.
Minor to moderate coastal flooding will become a concern during high tide times starting Sunday morning from the Jersey Shore to North Carolina as these strong northeast winds blow water toward the coast. Large and continuous waves will also cause severe erosion of the beach.
Rain from the low pressure system may occasionally move onto the beach between southern New England and Florida through the middle of next week, but should not result in a complete wash-off on beaches on any given day. Later in the week, the dip may reverse toward the southeastern United States and increase the chance of rain over parts of the southeast coast.
Due to the risk of rip currents, you are advised to be careful if you have beach plans for Mother’s Day or any day next week. According to the National Weather Service, a Average 60 people Rupture currents are killed every year in the US So far this year, rip currents have already been blamed on rip currents. 14 deaths.
Many beaches use colored flags to warn visitors of the current rupture dangers.
If you see the green flag, strong currents are not expected that day, so you should be able to swim safely. However, beware of yellow and red flags. A yellow flag indicates a moderate risk of strong rip currents, while a red flag indicates a high risk. Use extreme caution when entering the water if a yellow or red flag is placed on the beach.

Subtropical development is not excluded
It’s not out of the question that this low pressure system meandering off the East Coast will briefly turn into a subtropical depression or subtropical storm next week. A storm classified as subtropical means it has characteristics of both a tropical and non-tropical cyclone (the low pressure system you’ll typically find over land in the United States).
National Hurricane Center Issues Routine warnings For subtropical depressions and subtropical storms, just as for tropical depressions, tropical storms, and hurricanes.
The odds of this happening are low, but offshore, if it turns into a subtropical storm with winds of at least 40 mph, it will earn the name “Alex,” the first of the Naming list for the 2022 Atlantic hurricane season.
Although hurricane season doesn’t officially start until June 1, All the past seven seasons have generated at least one storm before that date.
Regardless of what this system is called (or not called), the effects along the East Coast will be the same as mentioned above.
