Miami woke up warm and sticky Tuesday, sitting around 81°F with light east winds and not much relief in sight. A Heat Advisory is in effect from 11 a.m. to 7 p.m., with forecasters warning that heat index readings could land between 105 and 109°F this afternoon. The official high is expected near 91°F, and most coastal spots should stay largely dry through the day.
Afternoon Heat And What To Expect
Temperatures will ramp up quickly after mid-morning and peak in the early to mid-afternoon. Heat index values are expected to hit advisory levels around noon and linger into the late afternoon. Southeast winds near 8 to 10 mph will keep conditions muggy while also limiting stronger storms right along the coast. Advisory details and safety tips are available from the National Weather Service office in Miami, according to NWS Miami.
Lower Rain Chances But Interior Storms Remain Possible
Forecasters say a corridor of Saharan dust is tamping down widespread storm development along the east coast, so most neighborhoods will only see a small chance of a passing shower. The better odds for pop-up thunderstorms sit across interior areas and the western side of South Florida this afternoon. Any storm that does form could be brief but capable of heavy rain and gusty winds. The timing of the sea-breeze will help decide where storms flare up, typically after mid-afternoon.
Cooling Centers And Safety Resources
Miami-Dade is operating staffed cooling sites at libraries, parks and community centers for anyone who needs an air-conditioned break. Locations and hours are listed on the county cooling sites page, according to Miami-Dade County. Among the options: Clark Government Center (111 NW 1st St) and Model City/Caleb Center (2211 NW 54th St), which run extended hours during heat season. Outreach groups are also stepping up services for people experiencing homelessness; residents are encouraged to call local hotlines or county resources for help finding a cooling site.
Plan For Your Afternoon
If you have to be outside, try to avoid the hottest stretch between roughly 11 a.m. and 5 p.m., drink plenty of water, and take frequent breaks in the shade or in air-conditioned spaces. Keep tabs on local forecasts and watch for fast-forming storms, especially if you are heading inland later in the day. If someone shows signs of heat illness such as heavy sweating, dizziness, nausea or confusion, move them to a cool place right away and call 911.
