Florida’s Ochlockonee River can see tornado rise as high as 4-5.5 metres, and some separated locations can also see tornado rise approximately 6 metres high.
This is a severe tornado rise projection, and comparable to Hurricane Laura’s surge in Louisiana in 2020. United state record-breaking tornado rise continues to be Hurricane Katrina with 8.53 metres (28 feet) throughout southerly Mississippi.
Threat for significant flash flooding with downpours

The biggest storm size in background was Typhoon Tip in 1979, having a period surpassing 2,000 kilometres.
Helene is anticipated to be around 60 percent bigger than Hurricane Idalia, which triggered $3.6 billion well worth of damages. Even though Helene is anticipated to have a size near to 800 kilometres, it’s fifty percent of what Hurricane Sandy’s width remained in October 2012.
Despite the unanticipated time-out in task this storm period, keep in mind that we can still see harmful tornados create over the coming days and weeks. Coastal homeowners need to very closely keep an eye on projections and have emergency preparedness kits prepared to go long prior to a tornado ever before intimidates land.
