How many tornadoes has Missouri had this year so far?
The state of Missouri has already seen double the yearly average of tornadoes only halfway through the year, according to the National Weather Service.
The NWS shared on X that the state has had a very active weather season, with 43 tornadoes already accounted for so far. This number is two times more than the yearly average of 21.5 tornadoes while only half through 2025.

The majority of these tornadoes were rated EF-1 tornadoes with 86 to 110 mile-per-hour winds, making up 20 of the tornadoes experienced across the state.
EF-0 tornadoes with 65 to 85 mile per hour winds have been seen 10 times already in Missouri.
The state has also had nine EF-2 tornadoes with 111 to 135 miles per hour winds and three EF-3 tornadoes with 136 to 165 miles per hour winds.
Missouri has only had one tornado with an unknown tornado rating, leaving no damage to rate.
Compared to previous years, in 2024 the state had 47 tornadoes in total. The NWS reports other active years include 2006, when the state saw 75 tornadoes.
FOX 2 Severe Weather Specialist Chris Higgins said one big clue for this year's active severe weather season can actually be found in the Pacific Ocean.
The possible cause: the slowly fading La Niña in the central Pacific Ocean.
The cold water associated with La Niña and a warmer-than-normal pocket further north up towards Alaska enhance the northern branch of the jet stream.
That branch of the jet stream is a key contributor to the wind energy needed for an active severe weather season across the Midwest.
That wind energy helps contribute to storm rotation, and rotating storms produce our most violent severe storms. The active jet stream has supplied a constant flow of triggers, which is why severe weather events have come at somewhat regular intervals since March.

Heat advisories extended for Bay Area inland locations as hot weather to last into weekend
Large portions of the Bay Area and the Central Coast were under a heat advisory Thursday morning, which has been extended for what could be the hottest days of the year. The National Weather Service said a heat advisory was in effect at 10 a.m. for inland portions of the East Bay and South Bay, as well as the North Bay interior mountains. The advisory was extended through Saturday after forecasters originally said the heat wave would peak on Friday. In its daily forecast discussion, the Weather Service said Thursday would be the hottest day for coastal and bayshore areas with above-normal temperatures in the 70s and 80s, respectively. However, away from the coast, temperatures will be in the 90s to the lower 100s on Thursday, with some records for the day possible falling. KPIX First Alert Weather: Current conditions, alerts, maps for your area While coastal areas should begin to see some relief late Thursday afternoon as onshore wind conditions start to prevail, interior locations will remain in the grip of a heat dome emanating from the Four Corners area of the Southwest U.S. through Saturday with Friday being the hottest day of this round of heat, the Weather Service said. Further south in the Central Coast area, interior portions of Monterey and San Benito Counties are also under the heat advisory, while areas of the San Joaquin Valley will be under an extreme heat warning beginning at 11 a.m. Friday through 8 a.m. Sunday. The Weather Service said dangerously hot conditions are expected in parts of the Central Valley with temperatures reaching 105, along with warm overnight lows in the mid-70s to lower 80s. In addition to the high temperatures, forecast models show clouds are moving in from the south as monsoonal moisture reaches the Bay Area and Central Coast, the Weather Service said. While the models show enough moisture and unstable air to support storms, forecasters say there's no strong trigger to set them off, meaning the chance of thunderstorms is low but not zero. If any storms do form, they're more likely to bring lightning than rain, raising the risk of dry thunderstorms, with the best window for possible storm activity being Friday and Saturday, especially over the Central Coast, forecasters said.

Hurricane Erin Waves Toss Around Popular Ferryboat: 'Doesn't Look Fun'
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A video shared on social media shows the popular Block Island Ferry bobbing up and down as it battles vicious waves from Hurricane Erin on Wednesday night. Newsweek reached out to Block Island Ferry by email for comment. Why It Matters As of Thursday morning, Hurricane Erin was a Category 2 hurricane with maximum sustained wind speeds of 100 mph. After skirting the East Coast, the storm is beginning to turn further out into the Atlantic Ocean. However, it still generated impressive and dangerous waves along the Eastern Seaboard on Wednesday night, and a Rhode Island ferry was caught in the tumultuous seas. What to Know The Block Island Ferry had a rough go of it as it battled unsettled seas when coming into Block Island on Wednesday evening. "From@NBC10 viewer Judy on Block Island," NBC 10 chief meteorologist Mark Searles posted on X, formerly Twitter, with the video. "This is the Wednesday evening ferry coming into the Island. Doesn't look fun!" From @NBC10 viewer Judy on Block Island. This is the Wednesday evening ferry coming into the Island. Doesn't look fun! #HurricaneErin — Mark Searles (@MSearlesWeather) August 20, 2025 On Thursday, Block Island Ferry issued a service alert that said all traditional and high-speed ferry services were canceled due to "adverse sea conditions." The Block Island Ferry approaches a Rhode Island harbor on a bright day with a calm sea. The Block Island Ferry approaches a Rhode Island harbor on a bright day with a calm sea. Ray Geiger/Getty The ferry has several Wednesday evening trips, including one that leaves Point Judith, Rhode Island, at 4:45 p.m., 6 p.m, and 7 p.m. The ferry "offers year-round and seasonal ferry services from Narragansett or Newport, RI" to Block Island, which is around 9 miles south of Rhode Island's mainland and known for its summer destination activities. The ferry typically offers several voyages per day, with average round-trip tickets for adults costing around $20. Numerous ocean-related weather warnings were in place for Rhode Island's coast on Thursday, including a gale warning, a high surf advisory, and a small craft advisory. National Weather Service (NWS) meteorologists warned of dangerous seas in the alerts. "Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions," the small craft advisory for Narragansett Bay said. What People Are Saying One social media user posted on X in response to the video: "I've been on that ferry many times. Oh my that looks a little … stomach turning." Another said: "I enjoy rough seas. Looks like fun to me." Another said, including vomit emojis: "I would be green" An NWS gale warning for Block Island cautioned: "Strong winds will cause hazardous seas which could capsize or damage vessels and reduce visibility." What Happens Next The Block Island Ferry won't be operating on Thursday due to hazardous seas. Some of its ferry trips also have been canceled for Friday.

Hurricane Erin flooding, rip current threat to peak Thursday night
NEW YORK — The coastal flooding threat from Hurricane Erin will peak with Thursday night's high tide, and dangers from the storm will continue into Friday, meteorologists said. Gov. Kathy Hochul ordered the closure of all New York state beaches through Thursday night, but the National Weather Service warned of rip currents throughout the region until 8 p.m. Friday. 'The threat for beach flooding, beach erosion and escarpment and areas of dune erosion will increase with successive high tides through tonight,' NWS forecasters warned Thursday. 'This high surf will be combined with elevated water levels as we approach a new moon.' Waves are expected to peak at 12-16 feet high on Long Island on Thursday night, with high tide times varying up and down the island. Coastal communities in southern Queens and Brooklyn could experience flooding. Hurricane Erin is expected to move further out to sea on Friday, and the storm is not predicted to make landfall. The storm is still making impacts along the East Coast because of its massive size, measuring nearly 600 miles in diameter,which is twice as big as an average hurricane. Even as Erin has made its way north, the storm has continued kicking up rip currents up and down the coast. The National Weather Service warned of dangerous ocean conditions from Maine to South Florida on Thursday. Rip currents are expected to remain a threat to the tri-state area through Friday, even if beaches finally reopen. By Saturday, conditions are expected to be back to normal.
