Overview

• Alerts remain active through Sunday, covering Lima and 19 other departments across the highlands and adjacent regions.
• Forecast maximums on Sunday range from 21–34 °C in the northern sierra, 19–29 °C in the central sierra, and 20–32 °C in the southern sierra.
• Separate coastal advisories for Sept. 20–21 call for stronger winds that may lift dust and sand and reduce visibility, with gusts near 32 km/h in the north coast, 34 km/h in the central coast, 22 km/h in the south, and up to 35 km/h in Ica.
• Indeci urges households to secure roofs and windows, avoid vulnerable structures and hazards, drive with caution in dusty areas, and seek care for respiratory or allergic symptoms.
• The warm spell comes just before the seasonal change, with spring scheduled to begin Monday, Sept. 22 at 13:19, as coastal mornings may still see drizzle, fog and low cloud cover.
