Tropical storm conditions could begin on the east coast of Florida as early as Saturday when the storm makes its way northward on a threatening path along the coast.
“There is a risk of impacting the winds, heavy rainfall and storms that occur this weekend afternoon from the northeast coast of Florida and extend northward for the rest of the east coast of the United States until early next week, “the National Hurricane Center wrote.
North Carolina, in particular, can hit hard from the storm Monday through Tuesday, where Isaiah could fall to the ground.
Earlier this week, Isaiah dropped up to 8 inches of rain in southwestern Puerto Rico and wiped out more than 400,000 residents on the island.
The storm then rained through the Dominican Republic, reshaping its axis of rotation and strengthening more than expected.
Hurricane warnings occurred throughout the Bahamas, where Isaiah is likely to pass as a Category 1or 2 cyclone. A tropical storm warning also remains in place for the Dominican Republic and the Turks and Caicos Islands, as bands of Isaiah’s remaining rain eventually gave up the islands.
Alongside the state, tropical storm warnings have been warned for areas between Homestead and just south of Melbourne, Fla., Including the cities of Miami, Fort Lauderdale and Palm Beach. Lake Okeechobee is also under a warning. A hurricane clock is in effect from near Boca Raton in the north to the space coast.
The tropical threat occurs when the state of the Sun continues to increase with a sharp increase in coronavirus cases. Florida is suspending state testing of covid-19 in outdoor areas this weekend and next week, in anticipation of the storm.
Beyond the east coast, there may be a strong shave or a direct blow from Isaiah, which can be a hurricane when heading north.
At 11 a.m. Friday, Isaiah was a hurricane with maximum winds of 75 mph, centered 295 miles southeast of Nassau in the Bahamas. The hurricane has been battling the effects of the shear that temporarily weakened it on Friday. But the Hurricane Center found a view, which is the area of strong winds surrounding the center of the storm, trying to reform, “an indication that the cyclone is trying to reorganize.” In addition, the storm will pass over abnormally warm waters, which could favor further intensification.
The Hurricane Center predicts that Isaiah will continue its journey through the Bahamas as a Category 1 hurricane, moving near or along the southeastern Bahamas, Friday in the Central Bahamas, and Saturday near of the northwestern Bahamas.
“A wave of dangerous storms will raise water levels by up to 3 or 5 feet above normal tidal levels in windy areas off the coast of the Bahamas,” wrote the National Hurricane Center, which it also predicts between 4 and 8 inches of rain in the Bahamas. .
Impact of Isaiah at 48 lower
Although Isaiah is expected to take the next step Saturday night in the wee hours of Sunday morning, rain could begin in southeast Florida as early as Friday night.
Some models are pushing downtown Isaiah moving far enough west that a stop would occur in Florida, but it seems less likely at this time.
Wind gusts as high as 45 mph would be possible along the Florida shoreline, in addition to dangerous breaking currents, isolated water levels and very heavy rainfall. A wide 2 to 4 inch weekend with localized amounts of 6 inches is in East Florida over the weekend.
The totals would be higher, but the storm will move quickly.
Isaiah is then expected to continue to be a hurricane as it falls north, and possibly a landing will be made in Carolina on Monday as a Category 1 storm. heavy rains and floods and strong winds
The strength of the system when it reaches the coast is a major uncertainty, as it will largely depend on its track. However, the oceans are full of abnormally warm waters off the southeast coast, which could intensify fuel.
A farther runway inland will feature a weaker storm, while a more backward jump over land could favor a stronger landing.
Strong winds and surfing danger can hit coastal areas, while coastal flooding by storm surges or the rising storm in the water above normally dry ground is also a problem. The severity of these impacts will depend on the exact track and intensity of Isaiah.
Precipitation on the east coast
Regardless of whether Isaiah falls ashore along the east coast, there is a growing concern for a strip of heavy rainfall from Florida to New England.
There is no doubt that large areas are seen more than 4 inches from the system, but there are still specific times and amounts.
The extremely humid air “advocated” to the north by Isaiah will interact with a cold front that precedes a dive approaching the stream of lightning or trough. This will help focus rainfall and will likely cause at least isolated problems.
Storm shelter during a pandemic
The ongoing covid-19 pandemic complicates the decisions of both local emergency management officials in charge of ordering evacuations and opening shelters, as well as residents who may be forced to use them.
The American Meteorological Society on Thursday issued guidelines on shelter during a covid-19, highlighting “if you evacuate to a shelter, you are responsible for your health.” The document notes, however, that the states and municipalities that open the shelters will most likely allow social distancing and the use of masks, among other precautions.
They recommend that residents procure and bring their own sanitation supplies, following CDC recommendations.
The Federal Emergency Management Agency (FEMA) plans to rely less on field equipment deployed in areas where a community spread of covid-19 is taking place, rather than processing damage claims remotely. In addition, storm planning documents encourage officials to consider ordering those who are not vulnerable to storm surges or other flooding impacts.
One of the states hardest hit by the storm, Florida is in the worst shape when it comes to coronavirus cases, hospitalizations and deaths.
Currently, the state is fighting a sharp rise and a plateau is now possible in new cases. However, deaths from covid-19 have increased. The state set a maximum death toll on Thursday, with 252 deaths. Florida also registered 9,956 new cases Thursday, according to a Washington Post database.
During the week of July 23-30, Florida led all other states in the number of new cases per capita.
Cumulatively, Florida has recorded 461,379 cases, which is almost double that in Italy.
North Carolina ranks 16th on the list of states with the highest seven-day average of new cases, which is a more reliable indicator than one-day totals, with 1,900 new cases. This is slightly lower than its previous high of 2,024 new cases.
Impacts on Puerto Rico and Hispaniola
On Wednesday and Thursday, Isaiah erupted in Puerto Rico and the Dominican Republic as a tropical storm with gusts, and toppled the islands with heavy flooding that caused damage in Puerto Rico. Doppler radar estimated that up to 8 inches fell in the southwestern part of the commonwealth, where major flooding was reported in the Rojo Cabo neighborhood.
Images representing the collapse of various structures in the Yauco community appeared on social media.
In the Dominican Republic, the National Hurricane Center expected total rainfall to approach one foot locally. Heavy rainfall continued to affect the Dominican Republic and Haiti in early Friday, while central Isaiah moved north.
Haiti is extremely vulnerable to floods and landslides due to rampant deforestation that has plagiarized its landscape and left much of the land unstable.
Until Thursday, it was initially assumed that the high mountains of the Dominican Republic, which protruded up to 10,000 feet into the atmosphere, could destroy and weaken Isaiah’s inner circulation.
However, the storm’s most robust axis of rotation marked the elevated terrain, crept northwest along the Mona Passage (or the stretch of ocean between the Dominican Republic and Puerto Rico) and organized a new center. low level in the north of the island. This allowed Isaiah to intensify, its winds being built around its new low-level rotating column, while its old low-level center disintegrated and disintegrated.
Isaiah in historical perspective
Isaiah is the ninth so-called Atlantic storm of 2020, which does not usually develop until about October. It is the first “I” storm recorded more than a week ago, and the last domino that ended in a season, which also caused storms C, E, F and G to form the first records in the Atlantic: Cristobal, Edouard, Fay and Gonzalo. Including Isaiah, 2020 has produced five so-called storms in July, tied for most records with 2005.
It is the first time in record the last week of July produced two hurricanes (Isaiah and Hanna) in the Atlantic.
