Heavy rain lines up for Malaga on Monday as storms drift toward Murcia, Alicante and the Balearics

Monday, September 28, is the day to watch on the Costa del Sol due to an 80 percent chance of heavy rain in Malaga city, 100 percent from 6 am to midday, and 90 percent through the afternoon. The province is on Yellow Alert for adverse wet weather and possible storms. High temperatures are expected to drop to around 25°C. Some models predict Monday as the wettest day of the next fortnight with rainfall totals exceeding 50 liters per square meter.

Inland valleys often collect more water than the coastal areas, with Guadalhorce, Antequera, and the Axarquia areas being particularly vulnerable after a dry spell. Andalucia's 112 service has been upgraded to orange in some inland Malaga areas, with forecasts for more than 15mm of rain per hour and a possibility of storms. Western Andalucia takes the first band, with Cadiz and the Strait experiencing strong levanter winds that can cause messy wind rather than heavy rainfall.

Almeria city is expected to be cooler on Monday, with a lower daytime rain chance than Malaga. Inland areas such as Almanzora, Los Velez, and Levante Almeriense may still receive showers later in the day. Murcia and Alicante are also likely to see rain, with rain more likely from around midday in Alicante. The Balearics are expected to have broken cloud with a weak shower possible on Mallorca and Menorca, as well as mist patches.

However, Monday is not the main threat for the islands, with sea temperatures still high enough for a sharp cell if cold air arrives overhead. Tuesday is when the East and the Balearics deserve equal attention, with isolated storms being the primary risk rather than a continuous line of rain. The situation is fluid, and updates should be checked on AEMET and Meteoalarm before travel.

Extra caution is advised on dry riverbeds and mountain roads in Almeria and inland Alicante, where single cells can cause road closures.
