Hurricane Dorian: What You Need to Know

Category 4 Major Hurricane Dorian is barreling towards the US East Coast.  The storm, which has rapidly intensified over the past several hours, is expected to reach the Bahamas by Sunday afternoon.

What you need to know:

The Saffir-Simpson Scale:
Category 5: 157+ mph - Catastrophic Damage
Category 4: 130-156 mph - Catastrophic Damage
Category 3: 111 - 129 mph - Devastating Damage
Category 2: 96 - 110 mph - Extensive Damage
Category 1: 74 - 95 mph - Some Damage

As of the evening of August 30, 2019, Hurricane Dorian is a category 4 major hurricane with sustained winds of 130 mph and a central pressure of 950 millibars.

The current National Hurricane Center forecast cone keeps Florida in the cross-hairs. This afternoon, computer model guidance shifted the projected storm path eastward, placing locations from Miami to as far north as South Carolina under the threat of winds well in excess of 100 mph, excessive rainfall, and significant storm surge.

The 8 PM EDT update from the National Hurricane Center has a category 4 storm making landfall near Port Saint Lucie, Florida. While there continues to exist uncertainty in the track of this storm, should this occur, storm surge well in excess of 7-11+ feet is possible on the coast of central eastern Florida, with top sustained winds potentially exceeding 130 – 140 mph in a radius reaching tens of miles from the center of the storm.

Who in the United States mainland will bear the brunt of this storm is still unknown. The storm will make a turn northward as it is picked up by a ridge of high pressure situated over the western Atlantic. When this storm makes its turn northward is still uncertain. 

It is vital that everyone on the US East Coast from Miami to South Carolina – and even further north – be prepared to act quickly ahead of this storm. 

Please prepare now and stay updated on local guidance and evacuation information from the National Hurricane Center (nhc.noaa.gov), the National Weather Service (weather.gov), and your local emergency management office.

Weather360 will continue to keep you updated on the progress of this storm both here and on our Facebook page.

Be prepared and stay safe!

Massive Hurricane Florence to Slam the Carolinas

Hurricane Florence, now a major category 3 hurricane with winds in excess of 115 mph, is expected to restrengthen as it makes its way towards the coast. Storm Surge and Hurricane Warnings are in effect from Myrtle Beach, South Carolina, to the northern Outer Banks in North Carolina, with Hurricane Watches extending as far south as Charleston.

Although the effects of Hurricane Florence will begin to impact the Carolinas starting tomorrow afternoon, strong winds and heavy rain will continue to lash the region until the end of the weekend due to the storm’s unusual path.

This is the  18z 9/12/18 run of the NAM 3km computer model depicting an extremely intense Hurricane Florence approaching the Wilmington, NC area.

For the past several days, computer model guidance has shifted to suggesting that Hurricane Florence will begin to slow down and proceed to parallel the coastline come Friday evening. The storm’s unusual path will force extremely dangerous winds and storm surge across a swath of land extending from the Outer Banks to South Carolina, placing millions under the threat of life-threatening conditions. Unfortunately, these conditions will only be compounded and exacerbated by the upwards of 3 feet of rain forecasted to fall in some areas.

The National Hurricane Center is forecasting winds to exceed 120 mph upon Hurricane Florence’s arrival near the coastline, with a storm surge exceeding 9-13 feet in some locations, making this storm extremely dangerous for those in its path.

If you have been ordered or asked to evacuate, please heed these orders immediately before it becomes too late to do so. All preparations for this storm should be completed immediately.

Hurricane Matthew Bears Down on Caribbean, Poses Threat to US

The monster  category 4 Hurricane Matthew is now beginning its path of destruction as it nears the northern Caribbean Islands. Up to over a foot of rain is expected over a wide swath of Haiti, Cuba, and Jamaica, creating the possibility for mudslides and flash flooding.

The National Hurricane Center has forecasted the storm to barrel through The Caribbean and The Bahamas before potentially impacting the US.

Hurricane conditions can be expected across Jamaica, eastern Cuba, and all of Haiti over the next 48 hours, and hurricane conditions are increasingly likely for large swaths of the Bahamas as well as The Turks and Caicos.

After about 72 hours out, the forecast becomes a bit less certain, as it begins to be reliant on, multiple factors, for now, we’ll focus on two.

  • Factor 1: The low pressure system in the Pacific Northwest is weaker than expected, meaning that once it reaches Hurricane Matthew on the East Coast (if at all), it will not be able to slingshot the storm away from the coast as previously thought.
  • Factor 2: The high pressure system in the Atlantic is much more dominant than expected, indicating that it may act as a block in Matthew’s path, forcing it much, much closer to the coast, as reflected in last night’s shift in the spaghetti model plots.

*Hurricane Matthew is an extremely dangerous storm, it is highly recommended to prepare and evacuate as ordered by your local governments should they do so. Please consult The National Hurricane Center at http://www.nhc.noaa.gov for more info.*

Major Hurricane Matthew Taking Aim at Carribean

Hurricane Matthew, now a major hurricane, has undergone rapid intensification over the past 24 hours. The National Hurricane Center has posted Hurricane Watches for Jamaica, as the storm is expected to make landfall there as a category three storm in a few days. After making landfall in Jamaica and traversing Cuba, Matthew is expected to reemerge over The Bahamas as a strong category 2 or weak category 3 storm.

Pictured above is the HWRF computer model simulated Infrared Satellite image for Wednesday October 5. This image was provided by Tropicaltidbits.com.

As far as forecasting the track and intensity of Matthew after this point, not much can be said besides that the storm will either skim the Southeast’s coast before turning out to sea, or the storm will ride parallel near to the coast all the way up to Canada. Either way, Hurricane Matthew poses a serious threat to life and property in locations ranging from the Caribbean to the Eastern Seaboard. More updates will be available here, and on our Facebook page over the following several days, but for official information, please consult The National Hurricane Center at http://www.nhc.noaa.gov.

Florida and The East Coast are Bracing for Hurricane Hermine

Hurricane Hermine will make history tonight as it will be the first storm of its status to make landfall in Florida in over a decade. Over the past week, what is now Hurricane Hermine went from being an area of exposed low-level circulation to what is now an organized storm capable of producing winds of 75 MPH as well as a storm surge of up to 8 feet on the coast. After impacting Florida tonight, the storm is expected to skirt the Southeast coast with winds exceeding 50 MPH before  moving out over the waters off the Mid Atlantic coast. The following is an image from The NHC displaying the expected track of Hermine as well as current watches and warnings.

On The Gulf Coast, Hurricane Warnings are still in effect for The Big Bend region of Florida, and Tropical Storm Warnings remain in effect for areas on The Panhandle as well as areas around Tampa.

This storm poses a serious threat to both life and property and has the potential to affect millions across The East Coast. Please consult the National Weather Service at weather.gov for your local watches, warnings, and advisories.

Tropical Depression Nine Expected to Become a Tropical Storm Today; Track Uncertainty Remains in the Long Term

Tropical Depression 9, the swirling mass of clouds just to the north of The Yucatan in the image to the left, is expected to intensify into a Tropical Storm sometime over the next several hours. The warm waters of The Gulf combined with little shear has finally allowed this storm to grow rapidly over the past couple of days. The National Hurricane Center (NHC) has issued Hurricane Watches as well as Tropical Storm Warnings for much of the Big Bend area of Florida north of Tampa. Although the storm is not currently expected to become a hurricane before landfall,  it will come close to doing so with sustained winds of about 65 MPH, so Hurricane Watches are still in effect for the area. Although a sort of model consensus has been reached regarding the short term for this storm, mayhem continues as some computer models have begun to indicate a shift to the west once it passes North Carolina. If this storm were to shift to the west as now indicated by some of the more trustworthy computer models, it would mean that impacts from this storm would be felt as far north as New England.  As of now, The NHC has put a 50% chance of a 3 to 5 foot storm surge occurring in The Long Island Sound, but until the computer models receive more information, it is unlikely we will know the exact track.  More updates will ne available here over the next several days, but please visit The National Hurricane Center at nhc.noaa.gov before making any decisions.
