Humid and hot end to South Florida work week, a few shower possible
The chance of rain is low but a few isolated showers will be possible.
There is a low risk of rip currents along the Atlantic beaches and the UV index is extreme. There are no alerts or advisories for boaters along the Atlantic or Florida Keys waters.
Over the weekend a tropical wave will move across the Florida straits and could inject a bit more moisture across South Florida. Although it will not be a washout, there will be the potential for scattered showers and a few storms on Saturday and Sunday.
Temperatures will remain near average with the low 80s in the morning and highs soaring to the low 90s in the afternoon under mostly sunny skies. When the humidity is factored in, it will feel like the triple-digits. The National Weather Service may issue heat advisories if heat indices reach 105 degrees,or higher, for two hours or more.
There will be a pleasant east breeze of 5 mph to 10 mph.
Early next week there is a 30% chance of rain. Spotty showers will be possible on Monday and Tuesday. The chance of rain rises late next week. Highs will stay seasonably hot in the low 90s.

What to know about powerful Hurricane Erin as it heads toward the US East Coast
Island communities off the coast of North Carolina are bracing for flooding ahead of the year's first Atlantic hurricane, Hurricane Erin. Although forecasters are confident that the storm won't make direct landfall in the United States, authorities on a few islands along North Carolina's Outer Banks issued evacuation orders and warned that some roads could be swamped by waves of 15 feet. The monster storm intensified to a Category 4 with 140 mph maximum sustained winds early Monday while it started to lash the Turks and Caicos Islands and the southeast Bahamas, according to the U.S. National Hurricane Center in Miami. Stronger, bigger Hurricane Erin forecast to create dangerous surf along US coastTropical storm warnings were in effect for the southeast Bahamas and the Turks and Caicos Islands, the hurricane center said. Here is what to know about Hurricane Erin. Forecasters say Erin will turn northeast — and away — from the eastern U.S. Still, the storm is expected to bring tropical storm force winds, dangerous waves and rip currents to North Carolina's coast. That is according to Dave Roberts of the National Hurricane Center. Coastal flooding in North Carolina is expected to begin Tuesday. Evacuations were being ordered on Hatteras Island and Ocracoke Island along North Carolina's Outer Banks even though the storm is unlikely to make direct landfall. Authorities warned that some roads could be swamped by waves of 15 feet. The orders come at the height of tourist season on the thin stretch of low-lying barrier islands that juts far into the Atlantic Ocean. There are concerns that several days of heavy surf, high winds and waves could wash out parts of the main highway running along the barrier islands, the National Weather Service said. Some routes could be impassible for several days. Portions of Highway 12 on Ocracoke and Hatteras Islands are most at risk for storm surge, National Hurricane Center Director Michael Brennan said. Erin's outer bands hit parts of Puerto Rico and the Virgin Islands with heavy rains and tropical-storm winds on Sunday. Storm surge is the level at which sea water rises above its normal level. Much like the way a storm's sustained winds do not include the potential for even stronger gusts, storm surge doesn't include the wave height above the mean water level. Surge is also the amount above what the normal tide is at a time, so a 15-foot storm surge at high tide can be far more devastating than the same surge at low tide. Erin's strength has fluctuated significantly over the past week. The most common way to measure a hurricane's strength is the Saffir-Simpson Scale that assigns a category from 1 to 5 based on a storm's sustained wind speed at its center, with 5 being the strongest. Erin reached a dangerous Category 5 status Saturday with 160 mph winds before weakening. It is expected to remain a large, major hurricane into midweek. 'You're dealing with a major hurricane. The intensity is fluctuating. It's a dangerous hurricane in any event,' the hurricane center's Richard Pasch said. Although Erin is the first Atlantic hurricane of the year, there have been four tropical storms this hurricane season already. Tropical Storm Chantal made the first U.S. landfall of the season in early July, and its remnants caused flooding in North Carolina that killed an 83-year-old woman when her car was swept off a rural road. And at least 132 people were killed in floodwaters that overwhelmed Texas Hill Country on the Fourth of July. Just over a week later, flash floods inundated New York City and parts of New Jersey, claiming two lives.

How Hurricane Erin Made History Without Even Making Landfall
The Atlantic's first hurricane of 2025 wasted no time making history. Hurricane Erin will be remembered as one of the fastest-strengthening Atlantic hurricanes on record, with perhaps the fastest intensification rate for any storm earlier than September 1, CNN reports. At 11 a.m. ET on Friday, August 15, Erin was a Category 1 hurricane, according to the National Hurricane Center. Over the next 24 hours, this storm strengthened significantly. By 11 a.m. ET on Saturday, the NHC declared Erin a 'catastrophic' Category 5 hurricane. Since then, Erin has weakened into a Category 4 storm, but the extremely rapid intensification it underwent over the weekend points to a troubling phenomenon largely driven by rising global temperatures. If much of this sounds familiar, you may be remembering Hurricanes Helene and Milton. Hitting in the fall of 2024, both of these storms rapidly intensified before slamming into the U.S. East Coast. Rapid intensification occurs when a tropical cyclone's maximum sustained wind speed increases by at least 35 miles per hour (56 kilometers per hour) within a 24-hour period, according to the NHC. Like Helene and Milton, Erin rapidly intensified over higher-than-average sea surface temperatures. Forecasters predicted this would happen as the storm moved into the Caribbean, but Erin exceeded their expectations, strengthening into a Category 5 storm practically overnight. This may be due in large part to the fact that the Atlantic Basin is experiencing a marine heatwave. Heat adds energy to tropical cyclones, priming them for rapid intensification. Category 5 hurricanes are relatively rare in the Atlantic Basin. Erin is one of just 43 on record, according to CNN. That said, roughly one quarter of these storms have occurred since 2016—a statistic that underscores the effects of climate change on hurricane season. Multiple studies show that rapid intensification is becoming more frequent and severe as sea surface temperatures rise. At the same time, human-driven global warming exacerbates another important storm-strengthening factor: atmospheric moisture. As such, the conditions that cause a cyclone to explode in strength within a short window have become mainstays of hurricane season. Since 1979, human-driven warming has increased the global likelihood of a tropical cyclone developing into a major hurricane by about 5% per decade, according to one recent study. Between 1980 and 2023, 22% of landfalling Atlantic tropical cyclones experienced extreme rapid intensification like Erin did, according to Climate Central. As we saw with Helene and Milton, rapid intensification makes hurricanes significantly more dangerous by reducing the amount of time communities have to prepare or evacuate. Both of these storms devastated their impact zones, causing billions of dollars in damages. Fortunately, forecasters expect Erin to remain offshore before tracking back out to sea, but that doesn't mean it won't be impactful. Despite not making landfall, Erin has already brought heavy rain, high winds, and widespread power outages to Puerto Rico, The Guardian reports. On Monday, August 18, the NHC warned of life-threatening rip currents and storm surge along the beaches of the Bahamas and the U.S. East Coast. Much of this Category 4 storm's impact remains to be seen, but it's clear that climate change is driving a new kind of threat in the Atlantic basin.

Cooler, Cloudier Stretch Ahead for Maryland
A cold front swept through Maryland early Monday, leaving behind cooler air, thick clouds and a steady northeasterly breeze that will keep conditions feeling more like late September than mid-August. After several warm days, highs Monday are only expected to reach the mid-70s to low 80s across much of the state, with even cooler readings in the mountains. The breeze off the Bay will help keep skies gray, and while most of Maryland stays dry, southern portions of the state could see a few light showers or drizzle this afternoon. Tonight, temperatures drop into the 60s, with patchy fog and mist possible under a low cloud deck. On Tuesday, more scattered showers could pop up, especially during the afternoon, but it won't be an all-day washout. Highs will once again stay below normal, topping out in the 70s. By midweek, all eyes turn to Hurricane Erin in the Atlantic. The storm is forecast to pass well offshore, but Maryland could still feel some indirect effects. Winds may pick up over the Chesapeake Bay and coastal waters, and dangerous surf will build along the beaches at Ocean City. Waves there are forecast to run 3 to 5 feet Tuesday, building to 4 to 6 feet by Wednesday evening. By Thursday, surf heights climb sharply to 6 to 10 feet in the morning and as high as 8 to 10 feet in the afternoon. Rip currents will be a significant concern for anyone heading to the coast. The latter half of the week looks fairly quiet as Erin moves farther out to sea. Highs stay in the low to mid-80s Thursday and Friday with only isolated showers possible, mainly in western Maryland. By the weekend, a stronger system approaching from the Great Lakes could stir up another round of showers and thunderstorms Saturday and Sunday. Some of those storms may pack a punch if humidity levels climb high enough.
