Prior to landfall, Elsa will bring torrential rain, gusty winds and storm surge to the western Florida Peninsula starting Monday evening as it churns north.
Conditions in the Florida Keys will begin to deteriorate Monday evening as Elsa draws closer. A storm surge of 1 to 3 feet is expected in the Keys, but higher levels are anticipated on the Florida Peninsula.
Though Elsa is a fairly compact system — tropical storm-force winds extend about 70 miles from the center — impacts will be felt across a significant portion of Florida.
“It should be noted that given the expected track, much of the west coast of Florida will be on the east side of Elsa, which is where the strongest winds, highest surge, and heaviest rains are expected to be,” the NHC wrote Monday.
Rain is expected through Wednesday, with 4 to 6 inches possible in some locations. The heaviest rain will be on the southwest coast of Florida from Tampa to Fort Myers.
The east coast of Florida will see occasional rain bands and isolated storms. The threat for isolated tornadoes also exists for central and south Florida through Tuesday.
Storm surge of 1 to 2 feet will be possible in the Florida Keys Monday and Tuesday as the storm passes. Higher storm surge, up to 4 feet, is expected farther up the Florida Gulf coast.
“After Elsa clears Florida, it is expected to move faster north-northeastward across coastal Georgia and the Carolinas Wednesday and Thursday before moving over the western Atlantic,” said the NHC.
Minor impacts — gusty winds and 2 to 4 inches of rain — are expected in parts of Georgia and the Carolinas later this week.
Record heat in the west worsens drought, another heatwave on the way
Temperatures ranging from 20-30 degrees above average last week increased evaporation, “further drying out soils and vegetation,” the Drought Monitor wrote.
As of Thursday, drought conditions existed across 93% of the West, an all-time high — with nearly 60% in extreme or exceptional drought, the two most severe conditions.
The drought will only worsen as temperatures will once again climb to record numbers this week.
“Excessive and oppressive heat across the Northwest will continue through at least the first half of the week where daytime highs will climb well into the 90s and 100s,” the Weather Prediction Center wrote Monday.
More than 40 heat records are in jeopardy this week as temperatures climb to 15 degrees above normal for this time of year.
“That may not seem like much, but it equates to an average of nearly 300 billion gallons of water evaporating from Lake Mead every year,” said CNN meteorologist Pedram Javaheri.
“About 40% of that evaporation goes poof in the sizzling summer months of June through August,” said Javaheri. That’s enough water to supply 75,000 homes for an entire year in the Las Vegas Valley.
Seen from space
The image shows just how hot the surface of the Earth got during the heat wave. One interesting thing to note is that during a heat wave, the ground temperature can be much hotter than the air temperature.
According to this image, the ground temperature in Seattle got as hot as 120 degrees on June 25, and that was before the excessive heat moved in.
Weather in focus
A fast-moving wildfire forced more than 1,000 people to evacuate and devastated the town of Lytton, Canada, one day after it recorded the nation’s all-time heat record.
Lytton Mayor Jan Polderman told CNN affiliate CTV News Friday that within minutes on Wednesday, “there was fire everywhere,” leaving no time to knock on doors and tell people to evacuate.
The fire destroyed “most homes and structures in the village” of Lytton and several residents are unaccounted for.
The weekly weather number
“March comes in like a lion and goes out like lamb.”
While the saying most likely started as a reference to astronomy — referencing the position of the constellations Leo (a lion) and Aries (a ram, or lamb) in the night sky — it quickly evolved into a succinct summation of March’s changing weather as the seasons change from winter to spring in the Northern Hemisphere.
This proverb means that March is a month in which you can experience a lion’s fierce roar of frigid cold and the long white teeth of biting winds. At the same time, you can experience the warmth of fluffy white fleece and the innocent kiss of sunshine like a docile newborn lamb.
Typically across the US, the month of March is still in the grip of winter, providing more of the same brutal cold, wind and snow, especially in the first days of the month. But as the month moves along, it often leads to glimpses of spring’s beauty and warmth.
