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 National Hurricane Center’s official track guidance as of 8 PM EDT on August 30, 2019. Hurricane Warnings (red) and Hurricane Watches (pink) have been issued for the Bahamas. This graphic depicts the potential storm center paths – not the potential extent of storm impacts.

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 (, the National Weather Service (, 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!

Hybrid Storm Takes Aim on Northeast

Tropical Storm Philippe has merged with a cold front off the coast of Delaware. The new center of low pressure is rapidly intensifying and continuing to push tropical moisture northwards. The core of the storm, as forecasted by nearly all computer models over the past 24 hours, is developing rapidly and, once onshore, is expected to bring with it wind gusts that could reach hurricane force. Today also happens to be the five year anniversary of the landfall of Hurricane Sandy, and the six year anniversary of the Halloween Snowstorm of 2011. This storm, although not as strong as either of these two infamous events, shares multiple, peculiar characteristics with both storms, including but not limited to the ‘negative dip’ in the jet stream, an atmospheric condition responsible for Sandy’s ‘sharp left turn’ into the Mid-Atlantic, as well as its combining with another storm system to create a hybrid-superstorm.

Northeast US Radar as of 6:25 PM Eastern Time.

The National Weather Service has issued a high wind warning for the entire NYC Metro Area, meaning that high winds will likely cause widespread power outages and will cause fallen items to block roadways. A flood warning is also in effect for the area, meaning that conditions are favorable for roadways and other low-lying locations to flood due to the excessive amount of rainfall. If travel is necessary, exercise extreme caution going into tonight and into tomorrow.

As Atlantic Hurricane Season Winds Down, Western Mexico Faces Major Hurricane Threat

10/22/15 8:00 PM AST: Hurricane Patricia strengthens rapidly to a Category 4 hurricane, Hurricane Warnings in place.

Although the Atlantic Hurricane Season is winding down, a massive Category 4 Hurricane Patricia is quickly moving towards the Central Mexican Pacific coastline.  This monster storm will also help bring massive amounts of rainfall to these areas along with parts of the Southern United States over the next several days.

The Forecast

At this time yesterday, Hurricane Patricia was only a Tropical Depression with sustained winds of only 35 MPH, and the forecast track was only suggesting the landfall at a maximum of a Category Two storm on the Mexican Coastline.  So what happened?

Well, since yesterday at this time, the forecast models have shifted as to support massive quick development of the storm due to warm ocean waters, and minimal wind shear.  Even though the official forecast track yesterday called for a moderate hurricane impact on the Mexican Coastline, some computer models such as the HWRF and the GFDL (Hurricane Computer Models) suggested that at least a potential Category Three storm impact was possible starting late on Tuesday.  These same computer models have steadily suggested a more violent impact since then.

For anyone with interests across along the Central-Pacific Mexican Coastline, please continue to monitor the storm and visit the NHC’s website for more information.


BREAKING NEWS:  Multiple tornado warnings issued last night for places in Virginia, Maryland, Delaware,  Pennsylvania, and New Jersey

The remnants of Tropical Storm Bill, while moving over Virginia still Tropical Depression Bill, brought in several lines of extremely dangerous and severe thunderstorms accompanied with rotation sufficient enough to produce tornadoes.  These thunderstorms also dumped whatever was left of Bill’s moisture as well, in some places over 3 inches of rain fell in less than an hour.  There were many flash flood, river flood, and flood warnings issued for areas from the Midwest to New Jersey last night as well, causing the need for some high water rescues by local fire departments and others.  For anyone anywhere in the United States that may be impacted by a tornado (basically everywhere), remember that although it may be interesting to watch and videotape a tornado or any type of severe storm, whenever the warning goes out for you, take all precautions and heed every warning in order to stay safe.

Rain is moving into our area tonight

The remnants of Bill, still a Tropical Depression with winds of 20 MPH, is expected to move right over the New York Metro Area tonight and tomorrow, bringing with it heavy rains and some gusty winds.  The amounts of rain that will fall in and around the city will likely be no more than an inch or two, with the exception in some localized areas.  Mainly, this storm system will be a rain maker that will start out the week with soggy conditions, but let this not be any premonition for the rest of the week, for drier and higher   temperatures can be expected.  Tonight and tomorrow of you are heading outdoors or planning to head outdoors, we at Weather 360 do advise you keep an umbrella handy invade of a sudden downpour.


As Bill made landfall south of Galveston, Texas yesterday, it began its track to to Oklahoma.  Although Bill, now a Tropical Depression, has weakened, it is expected to stay organized as it is and even strengthen slightly before weakening while dumping the majority of its moisture on southeastern Oklahoma.  In areas such as northeastern Texas and eastern Oklahoma, rain amounts could range anywhere from 4 to 8 inches, potentially causing extreme flooding of streams, rivers, and low lying areas susceptible to inland flooding.  At the moment, Bill still remains fairly organized and is moving across Texas into Oklahoma, before significantly weakening to a remnant low and traversing the rest of the country until reaching the Northeast.  Once in the Northeast, the remnants of Bill will dump any last bit of moisture it has in the form of rain showers and the occasional thunderstorm.

Recently, rivers in the areas that are expected to see rain soon have flooded, some breaking historic records, this means that there is the possibility of large flooding to happen again with the heavy rains expected to come, so keep yourself safe by heeding all warnings set out by your local NWS (National Weather Service) office.


This morning the NHC classified an area of disturbed weather with winds of 60 MPH with a well defined center of circulation as the second Tropical Storm of the year and the second Tropical Storm to make landfall this year in the United States, Tropical Storm Bill.  Currently, areas from the Louisiana border with Texas to the Mexican border near Brownsville are receiving some storm surge and winds in excess of 60 MPH along with torrential rains moving ashore.  The   NHC has issued Tropical Storm Warnings for the majority of the Texan eastern coast.  Several computer models are hinting (if not all of them) at the possibility of this storm maintaining at the very least Tropical Depression status several hundred miles inland, possibly to areas as far from the coast as Illinois or Indiana.  This storm is also bringing torrential rains to traverse the country as an abundance of tropical moisture comes through via Tropical Storm Bill. So, over the following days, rain will continue to spread over hard hit areas by flooding just about a week and a half ago, potentially bringing back severe flooding to areas susceptible to flooding.

For anyone in areas that are on the coast in Texas that will be impacted by Tropical Storm Bill, remain indoors unless absolutely necessary, and if you just go outdoors, exercise extreme caution and heed all warnings set out by the NHC.

Stay safe!


Current Invest 91L (As of 7:00 PM EST June 15th 2015), is now expected to become Tropical Storm Bill later on this night before making landfall somewhere between Port Lavaca, Texas and Galveston, Texas.  This storm already has sustained winds of about 45 MPH and is quickly developing a more organized center of circulation.  This storm will dump anywhere between 2 and 8 inches of rain from the Texas coastline to Indiana and Ohio before losing all of its remaining moisture over land.  Current invest 91L will also likely maintain its strength for several hundred miles inland as a Tropical Storm with winds above 40 MPH and torrential rains until it reaches the Missouri border with Kansas. For anyone living on or near the coastline between Galveston and Port Lavaca, please consult the NHC or your local emergency management center, and for those who live near or on the shoreline of a river or stream that is prone to flooding, please keep yourself up-to-date with any advisories, watches, or even warnings that may come your way as a result of this storm system, and do not forget to finish up any emergency preparations before the storm hits you.

We will keep you up to date and for detailed information regarding the soon to be Tropical Storm Bill, consult first with the NHC, then come on over to our Hurricanes 360 page to see what we here at Weather 360 could do to help you ride out the storm.

Stay safe!

*We would also like to apologize for the mix up on our last post, Invest 91L is the storm in the Gulf of Mexico, Invest 90L was Tropical Storm Ana in early May before it developed.
