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!

2019 Hurricane Season Outlook

Colorado State University has recently released its 2019 Hurricane Season Outlook and is calling for a slightly below average hurricane season. The Colorado State University outlook for the Atlantic Hurricane Season has long been one of the staples used in the long-term forecasting of how violent or active a particular hurricane season will be.

This year, the CSU forecast (as of April) is calling for an expected total of 13 named tropical cyclones (the average is 12), 5 hurricanes (the average is 6), and 2 major hurricanes (the average is 3). This forecast is based on various points of data, including recent measurements indicating that the Tropical Atlantic is slightly cooler than average for this time of year. Check out the full report here.

CANSIPS shear estimate

CANSIPS shear estimate 2
Above are computer model forecasts, made available by TropicalTidbits.com, for this coming hurricane season. This particular model, the CanSIPS, is forecasting increased areas of wind shear (generally less favorable for hurricane development) across the lower Caribbean from August to November. This by does not rule out the presence or development of hurricanes or other cyclones in the Caribbean Sea.

The Atlantic Hurricane Season begins on June 1 and lasts until November 30, during which time, as with any year, there will most likely be several potentially life-threatening cyclones in the basin. Despite the slightly reduced risk for tropical cyclones, please remain vigilant throughout the late spring, summer, and fall for further developments.

If you live in an area prone to hurricanes or tropical storms, now is the best time to get prepared. Ensure you have a proper emergency supplies kit and other essentials by visiting https://www.ready.gov.

Weather 360, Four Years On

Four years ago, in September of 2014, Weather 360 was first launched with one goal: To provide local and accurate weather forecasts. Since then, Weather 360 has served tens of thousands of people from dozens of countries around the world as it has expanded coverage from the 20 million people who live in the New York City Tri-State Area, to the entire Tropical Atlantic during Hurricane Season, and occasionally beyond.

Currently, after spending several seasons working on new methods of refining forecasting methods, Weather 360 is pleased to announce that its own systematic and statistical approach to weather forecasting – derived from data collected and analyzed in the New York City area – will be employed this winter to help facilitate the creation of our own forecasts. Formed from a variety of sources – whether it be from real-time data, shorter-range mesoscale computer models, or longer-range global computer models – the methods Weather 360 continues to expand upon to create and provide weather forecasts has only improved.

Weather 360 has also undergone many changes since it first came into existence: Beginning with launching a Facebook page nearly two years ago, reformatting its – well – format, and working on a YouTube channel that will effectively deliver information that cannot always be so easily delivered via text. Furthermore, to celebrate its fourth anniversary, Weather 360, in an effort to extend its ability to give weather-related information and advice to more people, has begun providing certain services in French and English for those who reside in French-speaking regions of The Caribbean, Canada, and The United States.

Once again, Weather 360 would like to thank all of its visitors for relying on us to provide their weather.

Thank you and stay safe!

Less Than Two Weeks After Irma, Maria Promises to Slam Caribbean as Monster Category 5

Hurricane Maria has intensified from a category 1 to a monster category 5 hurricane in under 48 hours. The now 160 mph storm is expected to strengthen further as it makes its first landfall in the eastern Caribbean before making a direct hit on the Virgin Islands and Puerto Rico. Maria possesses winds equivalent to that of an EF 3 to EF 4 tornado and is moving at less than 10 mph, meaning the worst of its winds will bear down on the same locations for up to 6 hours at a time (keep in mind that a tornado typically spends around 30 seconds to 2 minutes affecting one single location). The National Hurricane Center forecasts Hurricane Maria to make landfall in southeastern Puerto Rico as a category 5 storm with sustained winds of 160 mph. The already devastated US and British Virgin Islands can expect extreme winds and rain as well as storm surge over the next 48 hours. This will cause catastrophic damage across Puerto Rico and the Dominican Republic as well.

The National Hurricane Center’s cone of uncertainty regarding Maria’s potential track, the storm is also expected to expand as it approaches Puerto Rico and the Virgin Islands.

Following its landfall in Puerto Rico, Maria is expected to track into the eastern Bahamas as a category 3 or 4 storm as it continues to move northwestward, potentially impacting the US East Coast over the next week and a half.

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.

Joaquin Expected to Impact Bermuda, Watches and Warnings Issued

Weather Bulletin – 10/3/2015 2 PM AST

The National Hurricane Center in Miami Florida has issued a Tropical Storm Warning and a Hurricane Watch for the Islands of Bermuda.  The strong Category Four Hurricane Joaquin is now moving quickly to the northeast towards Bermuda.  Joaquin’s center is expected to pass within 75 miles to the west of Bermuda in about two days, as a potentially high Category Two, or low-grade Category Three storm.  Due to Joaquin’s potential proximity to the island nation, the  NHC urges residents to take precautions immediately and to be prepared for the worst.

We’ll keep you posted – Weather 360

Tonight crucial in any future development of Tropical Storm Erika

As of 5:30 PM EDT/AST

With the newest NHC track and intensity update of Tropical Storm Erika rolling out, it is time to really stop and think, what is the single most important factor in Erika’s development, what is most crucial in the short term?  The answer is for the most part clear, and cloudy, but it is Hispaniola at the moment…

Hispaniola and the Storm Shredder’s

Sounds like a band, right?  Anyways, the mountains spread across central and southern portions of the two-nation island do inhibit development of tropical cyclones by ripping to shreds their center of circulation in the lower levels.  The mountains of Hispaniola are anywhere between 6,000 and 10,000 feet, tall enough to disrupt the centers and  other clouds at the lower levels.  So really it all comes down to the mountains over the next 12 to 18 hours, and if Erika is strong enough to at the least reemerge after its encounter with the land masses.

Official Alerts:

Tropical Storm Warnings are in effect for the entire length of the coasts of The Dominican Republic and Haiti, along with The Turks and Caicos along with most of The Bahamas.

Tropical Storm Watches are in effect for northeastern parts of Cuba and for locations in the northwestern portions of The Bahamas.

Weather 360 will continue to monitor the progress of Erika over the next several days.

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.

Soggy next few days expected as Bill traverses the country

As Bill  swirls around over Oklahoma, it is starting to drift more and more eastward.  Bill is still considered a huge threat to millions as several inches of rain could induce more flooding across areas from Oklahoma to Rhode Island as it crosses the country, especially in areas that have undergone severe flooding just several weeks ago.  Be on the lookout for some thunderstorms in the Northeast and try to plan around potentially heavy rains on Sunday throughout the Northeast. Also, although slim, there is a potential for some severe storms to pop up in the NYC area on Sunday, so please heed all warnings set forth by the NWS.

Thank you and we hope you come again to Weather 360!

BILL EXPECTED TO MOVE ACROSS MIDWEST TONIGHT AND TOMORROW WHILE A 7.0 MAGNITUDE EARTHQUAKE OCCURS IN THE SOUTH ATLANTIC

BREAKING NEWS: A 7.0 MAGNITUDE EARTHQUAKE HAS OCCURRED ON THE SOUTHERN MID ATLANTIC RIDGE, THERE IS NO TSUNAMI THREAT FOR ANY LOCATION SURROUNDING THIS AREA.

Tropical Depression Bill

As Bill continues to swirl its way into Oklahoma, the rain bands extending into the Gulf of Mexico from its center are beginning to move northward as well.  The rain from this system is the biggest threat thus far for the remnants of Bill, with up to 8 inches of rain in southern Oklahoma, to several inches of rain expected to fall over a 500 mile long path across the United States over the next few days, to the possibility of severe thunderstorms, Bill has proved itself to be one large rain maker.

Okay, okay, we know that there will be large amounts of rain, but how will this affect me?  Well, as Bill dumps its remaining moisture over the US, already flooded rivers from just a few weeks ago that have not already returned to normal will pose a potentially catastrophic threat to anyone living on or near shorelines to rivers or streams. Also, in areas such as the Northeast, occasional downpours may cause flash flooding, which can take anyone by surprise.

Now that we have said how Bill may affect you, Weather 360 hopes that if you are to be impacted by any element of this storm, that you will be safe and heed all advisories, watches, and warnings set out by your local NWS (National Weather Service) office(s).
