Buresh Blog: La Nina is no more
NOAA has declared the weak La Nina that lasted just a few months as officially 'over'. While not particularly strong, this La Nina did seem to have some 'hallmark' impacts on the overall weather pattern over the Lower 48 of the U.S. including:
(1) big winter temp. fluctuations which included 18 freezes in Jacksonville (most freezes since 2010-'11) as well as a 'winter storm' in mid to late January that brought snow & ice to parts of North Florida & the Panhandle. (2) an active late winter into spring tornado season.
The image below shows the short mid winter period where La Nina conditions - a cooling of the equatorial Pacific - occurred.
The graph below shows an essentially neutral forecast for the ENSO (El Nino-Southern Oscillation) through the upcoming summer. If true, there would be no major implications for the Atlantic hurricane season which is forecast - as of right now - to be 'somewhat' above average.
There have been more than 5,000 severe storm (tornadoes, damaging winds, large hail) this year so far:

Forecasters closely monitor two more potential tropical systems in an extremely warm Atlantic
According to the National Hurricane Center, the first major hurricane would typically form in early September; this year, that occurred in mid-August. NHC Forecasters are closely monitoring two other tropical systems in the Atlantic. The National Hurricane Center said a tropical disturbance in Erin's wake in the central Atlantic has a decent chance of developing into a tropical depression by the weekend, while another disturbance, Invest 99L, located off the western coast of Africa, has a lower chance of developing into an organized storm. Early and late in the hurricane season, more storms form in the Gulf and in the Western Caribbean. But as we continue through August and into September, we have more of those storms that form off the coast of Africa and then move westward toward the United States. The track of hurricanes is determined by high pressure that sits out in the Atlantic. Depending on the configuration of that high, the storms can either wrap around and move northward between the East Coast and Bermuda, similar to what we're seeing with Erin this week. But if the high-pressure system is anchored differently, the storms can be funneled toward the Gulf Coast or even the Eastern Seaboard. Advertisement Tropical development shifts east as the season progresses and then south and west deeper in the fall. NOAA Advertisement This year, the The forecast is for up to five major hurricanes this year, with as many as 18 named storms, which include tropical systems. NOAA The season itself ramps up very quickly from this point forward, with the statistical peak on Sept. 10. From there, things taper off fairly quickly through the rest of September into October as the waters of the Atlantic cool. Hurricane season does not officially end until Nov. 30. For us here in New England, we still have not had a hurricane reach the shores of the area The number of hurricane strikes by counties here in the Northeast is highest over Cape Cod and the Islands. NHC Even if we don't have a hurricane, a tropical storm can still bring plenty of damage. The remnants of Sandy in 2012 and the remnants of Irene the year before both brought significant flooding, tree damage, and power outages to the Northeast. Even though these storms were not officially hurricanes when they reached our latitude, they still were formidable weather events. You can see the many hurricane strikes, below, that occurred from Texas up through Cape Cod from 1900 to 2010. There have been many hurricanes to hit the US, from Texas to Massachusetts, since 1950.

Weather Words: Rainbands
Rainbands are the long, curved bands of heavy rain and thunderstorms that spiral outward from the center of a tropical cyclone. Often stretching hundreds of miles, these bands are one of the most visible and dramatic features of hurricanes and tropical storms when viewed from satellite imagery. They help give these storms their iconic pinwheel shape. Within rainbands, weather conditions can vary dramatically. One moment might bring intense rainfall, gusty winds and even tornadoes; the next might offer a brief lull or lighter rain. As these bands rotate around the storm's eye, they can sweep over the same location repeatedly, leading to prolonged periods of rainfall and extreme flooding. Outer rainbands have been known to linger for hours or even days, bringing some of the worst damage to locations far from the center of the storm. While many tropical systems bring intense rainfall and flooding, Hurricane Harvey is one of the most extreme examples of what can happen when slow-moving rainbands set up over an area. The storm stalled over southeast Texas in 2017, unleashing relentless rain and flooding. Some areas received roughly 40 inches of rain in less than 48 hours. Rainbands also play a crucial role in the structure and strength of a hurricane. The most intense storms tend to have well-organized, tightly packed rainbands, while looser or more fragmented bands can signal a weakening system. For those on the ground, the arrival of outer rainbands is often the first sign that a hurricane is approaching, even if the storm's center is still far away.

FIRST ALERT WEATHER: Erin roughs up the beaches while it stays mostly sunny, hot
It's a mild but breezy morning. The morning commute looks largely dry but there may be an isolated shower moving in off the ocean. Breezy winds stick around through the day as Hurricane Erin passes Jacksonville's latitude today. There may be an isolated shower at times but lots of spots stay dry and hot. Erin brings us rough seas and surf at our beaches today and tomorrow especially. A HIGH SURF ADVISORY is in effect for our entire coast for waves up to 10-11 ft. A COASTAL FLOOD ADVISORY is in effect this afternoon. Watch out minor tidal flooding at times of high tide at the beaches and the St. Johns River. Winds change direction tomorrow, and while we stay largely dry, it will get hotter. Seas/surf will start to calm down Friday, then showers/storms really pick up on Friday and this weekend. TROPICS Hurricane Erin tracks north in the W. Atlantic, passing Jacksonville's latitude midday today almost 500 miles away. Tropical Storm Warnings and Storm Surge Warnings are in effect for the North Carolina Outer Banks. Erin lifts away from the U.S. and into the North Atlantic on Friday. Two other tropical waves are in the Central Atlantic way behind Erin. At this time, long-range forecast models either keep these systems out to sea, or don't even develop them. We have time to track these areas and the next name on the 2025 list is Fernand (pronounced fair-NAHN). Besides Erin, there is no threat to Florida for at least a week (and potentially longer).
