US weather forecast

It is reported by CNN that the Isaias storm, which has 75 mph winds, will be near the central Bahamas Friday night and move northwest Saturday as it moves near Florida's east coast. Southern and eastern Florida is expected to be hit with a maximum of 6 inches of rain, the hurricane center said. The northeastern portion of the state and coastal Georgia is due to get 1 to 2 inches of rain.

A hurricane warning is currently in effect for eastern Florida, the hurricane center said, though it is not clear where exactly the storm will hit. Some models indicate Isaias could hit Florida or skirt up the east coast of the US. A hurricane warning means that hurricane conditions are expected somewhere within the warning area.

Despite not knowing the exact path of the storm, states are still preparing. North Carolina Gov. Roy Cooper and Virginia Gov. Ralph Northam both declared a state of emergency Friday ahead of the storm.

According to National Weather Service San Juan meteorologist Gabriel Lojero, Isaias' exterior slammed Puerto Rico before it went over the Dominican Republic, all as a tropical storm on Thursday. It left 300,000 to 400,000 people without power in Puerto Rico.

It dropped 5 to 10 inches of rain, triggering flash floods and mudslides on the island, Lojero said.

Where Isaias will affect the US, and how intense it will be, was still uncertain.

Some forecast models show the storm slowing down and coming very close to the Florida coast Saturday and Sunday before getting near the Carolinas on Monday and Tuesday. In contrast, others curve the hurricane away from Florida and directly toward the Carolinas.

Either way, the storm could affect much of the US East Coast at some point into next week -- potentially bringing winds of tropical-storm strength as far north as Maine by early Wednesday, added CNN.

"The details are not very clear at all, especially considering the track uncertainty, but there is a notable chance of a hurricane moving close to the US East Coast, so the forecast continues to show that scenario," the NHC said in a forecast discussion Friday morning.

"Interests along the entire US East Coast should monitor the progress of Isaias and updates to the forecast," the discussion continued.

“Deadly heatwave' forecast for Southwest this weekend”, NWS warns

The National Weather Service has issued an Excessive Heat Warning for parts of Arizona, Nevada, and California, including Las Vegas and Phoenix. This warning signifies "dangerously hot conditions up to 120" and is in effect until 9 p.m. PST on Saturday.

"Heat of this magnitude is rare, dangerous, and deadly," said the Phoenix National Weather Service of the temperatures predicted today for much of western Arizona.

Temperatures in many southwest cities will reach over 110 degrees Fahrenheit this weekend, posing key health risks. Las Vegas is expected to reach 112 on Saturday, and Phoenix will hit 114 today. Palm Springs is forecast to hit 118 on Saturday, reported CNN.

The NWS is asking residents to stay safe by keeping hydrated and avoiding outdoor activities. According to the Centers for Disease Control and Prevention, extreme heat kills around 600 people per year. People with certain medical conditions, the elderly, and those without access to air conditioning are at particular risk.

A high-pressure system moving through the Southwest is bringing the heat, which will last through the end of the weekend. The heat combined with dry air and winds of up to 15 mph in some areas may also increase fire risk, says the NWS.

Warmer than average lows could lead to some uncomfortable nights in the Northeast and Southwest. Much of the West is expected to experience temperatures near or slightly above average, which may mean widespread average lows in the 50s. Near-average or slightly warmer than average temperatures in the Great Lakes and Southeast in August may translate to lows in the 60s or 70s.

Parts of the Plains, Mississippi Valley, and South that could trend slightly cooler than average may find lows in the 50s and 60s at times in August.

People are advised to take the following precautions to protect themselves, their families, and their neighbors.

Environment Canada said special attention may be needed when it comes to people who are more susceptible to heat such as infants, children, seniors, and those with pre-existing lung, heart, kidney, nervous system, mental health or diabetic conditions, outdoor workers and those who are socially isolated. Heat warnings are issued when very high temperatures are expected to pose an elevated risk of heat illnesses, such as heat stroke or heat exhaustion.
