With warmer weather comes more people heading outdoors for camping. It also comes with the risk of severe weather. AccuWeather spoke with several park officials on how to stay safe from storms.
Cooler and less humid conditions are settling in across the Northeast, while residents receive a brief respite as they pick up the pieces after tornadoes ravaged the mid-Atlantic on Thursday evening. Unfortunately, more storms are on the way to the region before the weekend is over.
"A potent short wave of energy will sweep across the Great Lakes to the Northeast on Sunday delivering the threat for damaging storms by Sunday afternoon," said AccuWeather Senior Meteorologist Matt Benz.
A short wave is a disturbance in the middle or upper part of the atmosphere which induces upward motion ahead of it, according to the National Oceanic and Atmospheric Administration (NOAA). This upward motion allow storms to develop.
"A couple of pockets of severe weather are likely in the Northeast on Sunday, and the pattern switch may eventually lead to a great deal of rain in the Southeast and parts of the Northeast," added AccuWeather Senior Meteorologist Alex Sosnowski.
Much of the Northeast has already had its fair share of rain this month, with many cities having received over twice the amount of average rainfall so far in July. Boston has recorded over three times its normal amount. With storms bringing heavy downpours on Sunday, the region will likely start August quite wet as well.
"Unlike last week where there was ample moisture and very warm temperatures, this weekend is a bit cooler and less humid," said AccuWeather Senior Meteorologist Matt Benz. This means severe storms are more likely to impact areas closer to the upper air disturbance anticipated to move across northern Pennsylvania through Upstate New York and northern New England.
Cities in the path of this storm include Binghamton and Albany, New York to Williamsport, Pennsylvania, could all be on the edge of this severe risk as well.
It's currently looking as though the Philadelphia area, previously damaged by several tornadoes on Thursday evening, won't be directly in the line of fire for these severe storms.
"If moisture levels can rebound sufficiently into Sunday evening, along with higher temperatures, that threat for thunderstorms may creep southward across Pennsylvania and New Jersey and closer to areas that were hit hard by tornadoes late last week," Benz said.
Another area forecasters are predicting to experience severe weather through Sunday evening is farther south, across the Carolina coast.
For both of these areas, expected impacts include flooding downpours, hail and damaging winds, with an AccuWeather Local StormMax™ of 80 mph.
Those spending time outside on Sunday should be extra cautious and aware of the situation, finding solid structures to take shelter in and checking the AccuWeather radar frequently. Flash flooding can occur, and motorists are reminded to never drive through floodwaters. Motorists should also be aware of changing visibilities in heavy rain.

Damaging winds can cause power outages when tree limbs fall on power lines, so it's important to be prepared for loss of electricity, including air conditioning. The Red Cross suggests that deaf and hard-of-hearing people take extra precautions to stay safe during weather emergencies.
There can even be some isolated tornadoes, forecasters say.
Especially after Thursday's disastrous tornadoes in the Northeast, forecasters want to emphasize the dangers of these forces of nature. They urge residents to have a means of receiving warnings and to have a plan in place in case a tornado comes their way.
It's important to know the difference between a tornado watch and a tornado warning when preparing for severe storms.
When a tornado watch is issued, that indicates that conditions are favorable for tornadoes to develop. With these watches, the necessary ingredients of a tornado may be present, but there is not yet any sign of a tornado. They are often issued hours in advance over large areas.
A tornado warning indicates that either a tornado has been sighted, or meteorologists have detected rotation that would indicate a tornado is likely present. Those under a tornado warning should seek shelter as soon as possible.
