Lomas del Sur — a residential development within the greater Guadalajara area — sees rain the way much of Jalisco does: driven by North American monsoon convective storms, intensified along the Pacific coast by hurricane moisture, arriving fast and unevenly.
One practical result: urban drainage failure over buried rivers and coastal storm flooding is something Lomas del Sur deals with regularly, in line with the broader pattern seen across Jalisco.
The rain radar behind Lomas del Sur's live map is built on CONAGUA (Comisión Nacional del Agua) data, refreshed every 5 minutes. Rather than a forecast icon covering the whole state, it shows exactly where precipitation is falling over Lomas del Sur right now.
Lomas del Sur follows the same rainy-season rhythm as the rest of Jalisco, with storm frequency rising sharply during the peak months.
Outside that window, Lomas del Sur settles into a calmer, more predictable stretch — consistent with the rest of Jalisco, though never entirely rain-free.
Storms tied to North American monsoon convective storms, intensified along the Pacific coast by hurricane moisture can build faster than a typical commute takes. A quick radar check first beats finding out halfway there.
Given that urban drainage failure over buried rivers and coastal storm flooding is a known pattern here, the useful question isn't whether it'll rain — it's when. That's what the radar answers and a forecast doesn't.
If you're unfamiliar with Lomas del Sur's weather pattern, the radar is the fastest way to get oriented — real-time, not a forecast for the whole region.
Whoever's planning a day in Lomas del Sur benefits from checking the radar directly, rather than relying on a forecast built for all of Jalisco at once.
Lomas del Sur is a residential development within the greater Guadalajara area. That's context, not a current forecast -- for real-time conditions, RainViewer's Lomas del Sur radar updates every 5 minutes with CONAGUA data.
That's a question the radar answers better than any forecast. Checking Lomas del Sur's live view shows whether the storm is minutes away or has cleared.
Urban drainage failure over buried rivers and coastal storm flooding is a recognized issue here, and traffic in Lomas del Sur can back up quickly once heavy rain starts. The radar helps time trips around it.
It's a real possibility in parts of Lomas del Sur — urban drainage failure over buried rivers and coastal storm flooding is documented across Jalisco, so checking conditions before a major storm is a reasonable precaution.
The drier stretch of the year offers the most reliable conditions in Lomas del Sur. Outside that window, checking the radar before outdoor plans is still worth doing.
It's a function of North American monsoon convective storms, intensified along the Pacific coast by hurricane moisture, producing tightly localized storms rather than uniform rainfall across Lomas del Sur. A forecast averages that away; a radar doesn't.
It does. RainViewer's radar for Lomas del Sur pulls CONAGUA data every 5 minutes, and the Essential plan adds 48 hours of history plus a short-term forecast.
