A tornado warning issued for portions of Grafton, Merrimack and Sullivan counties has been dropped. It was in effect until 2:15 p.m. but is no longer active.
The warning area included the communities of Grantham, Springfield and Croydon. In Grantham, trees were reportedly toppled and more than 1,000 outages were reported.
It’s not known if a tornado formed and touched down. The warning was issued because a potential tornado was radar-indicated.
Any time a tornado warning is issued, it’s important to head indoors to an interior room away from windows.
Other cells prompted severe thunderstorm warnings Thursday on what has been an active day. A severe thunderstorm watch is in effect for all of New Hampshire for Thursday until 9 p.m., according to the National Weather Service.
Any storm that forms may be accompanied by damaging winds, hail, torrential rain and frequent lightning. An isolated tornado is possible.
A heat advisory, meanwhile, is also in effect through 8 p.m. this evening for parts of interior New Hampshire — Strafford County, eastern sections of Hillsborough County and interior Rockingham County — as highs will push into the 90s with dewpoints in the 60s again for many spots in southern New Hampshire before a cold front arrives.
WEEKEND FORECAST
After storms wind down, things will dry out for the state, but temperatures won’t drop much for Friday and the weekend as highs will be well into the 80s to lower half of the 90s Friday, low to mid 90s on Saturday, except cooler coast, and mid to upper 90s on Sunday. There is a Slight chance of a thundershower Friday PM and Saturdy PM but the next good chance of showers and storms will come Sunday Evening into Monday.
That next system will help provide real relief from the heat and humidity by Monday night into Wednesday morning.
HOT WEATHER SAFETY TIPS
Health officials urge everyone to remember to drink plenty of water and make sure their pets are kept cool. Officials also reminded Granite Staters that children and pets should not be left in a hot car for any length of time because it can be deadly.
Anyone spending a lot of time outside should drink water every 15 minutes, take frequent breaks indoors or in the shade, wear tightly-woven clothing that blocks out light, use sunscreen, wear a hat, wear ultraviolet-light-absorbent sunglasses and limit exposure to the sun between 10 a.m. and 4 p.m.
Anyone overcome by the heat should be moved to a cool and shaded location and 911 should be called immediately.
